DW constant crashes, multiple OS/Devices

[Hertsmedia]

Hi everyone, I wondered, in desperation, if any of you (more patient) people can help please.

Mac Mini M1 2020 OS Monterey.

Since day one DW constantly crashes mid coding, literally disappears from before your eyes followed by error report. Previously did the same on Big Sur, so its not an OS issue, as such. Happens 4-5 times day, nothing else crashes .

I also have MacBook Air 2019, bought from family a few months back, brand new (wiped) Monterey install, with CC and DW duly installed from scratch. Use this for 2-3 hours a day in the morning. Same issue, yet completely different device and processor.

The whole DW interface without warning just disappears from view as I am actually writing code, the restore file it offers is usually pointless, it's lost previous entries..

ISSUE 2

Control/Command Z (Undo, CMD Z, CTRL Z for searchers) has a ridiculous habit of rewriting whole chunks of page code, especially on CSS files whenever I hit undo.

It will not only undo whole lines at a time instead of last few characters it destroys whole pages by inserting or removing spurious characters.

I have had TM save me a few times, once it wasted 2 hours of coding.

PLEASE help if you have any experience,  I am going to start videoing as i am preparing a claim for refund/comp  in a few weeks once I have collated enough evidence.

Thanks in advance.

DW does not typically re-write code unless it's attempting to resolve critical code errors within the document.

Validate code and fix reported errors.

- HTML https://validator.w3.org/

- CSS https://jigsaw.w3.org/css-validator/

If DW still misbehaves after all code errors are removed, switch to another Workspace. 

Failing that, Restore Preferences.  But make sure you backup your site definition settings, snippets and other settings first.

Thanks so much. 
It's not rewriting or correcting it's literally destroying code and breaking up lines way outside of where I'm even writing. I've had people watch it happen in real time. 
I've read other reports of the undo being broken so it's not just me.  For example, especially on css files if you add a rule or two, then start writing another, then hit undo it will not just delete the current word or two it'll delete the whole set, no other software does this. Maybe try, see if yours does it as both my macs behave the same. I'd be interested to know. 

As stated, it's doing the same on a brand new separate installation on the Air so it's unlikely a corrupted preference set on both. Both crash multiple times daily, the Air less than the mini. Lots of reports about crashing do not just me. 

I have  22 years of coding behind me using DW from the earliest versions and was perfectly happy with 5.5 until my new M1 Mac forced me to "upgrade" to CC. Within minutes I found things missing, like design time style sheets. I had to go buy a plug-in!

Thanks again for you reply, and suggested remedies. 

I'm going to try and capture it on video, then post it here. 

take care.

...on css files if you add a rule or two, then start writing another, then hit undo it will not just delete the current word or two it'll delete the whole set...

@Hertsmedia,

Does this happen in CSS Designer Panel or when manually editing CSS code directly?

If manually editing code, are you opening the CSS file from Files panel or just clicking the related files tab on top?   The former is a real document.  The latter is a virtual one.

There is also an option in Preferences > General tab to limit undo actions to active document.  I recommend you use that setting.  Otherwise, DW's new Undo can effect multiple documents  -- a "feature" that has confounded several users.

Thank you, again

I hand code everything, so this is in a CSS file writing directly. Add a rule, add another, add another and undo and whole lot goes.... or at least half. Up to a random point each time too.

I was aware of the limit undo fnc thanks, that's not the culprit. It's  frustrating rather than destructive but does mean I can lose a whole set of styles if I undo, maybe try, see if it does it for you?

I'm comparing lots of this to DW5.5 and 6 as that's where I was a couple of years ago, thought CC would be an upgrade albeit forced by hardware. Things like losing CSS design time and these other bugs/changes affect our workflow. Working in online applications/databases, if I told a customer we have upgraded them but taken away core functionality I think they'd moan a bit !! This transition hasn't been smooth especially with minimum 1 crash per hour on either the Mini or Air.

thanks again, let me know if the style rule thing does the same for you.

Design Time stylesheets disappeared from DW CC in 2013 I think.   If CSS poses problems for users, disable styles from your DW View menu.  View > Design View Options > Style Rendering > remove check from Display Styles. 

This has no effect on either Live View or Real-Time Preview. It only effects Design View.

With respect to Undo.  See my animated screen capture. Results are the same in any document (HTML or CSS) and with keyboard shortcut (Ctrl + Z).

Frequent crashes are a different matter.  If Restore Preferences didn't help you, contact Adobe Technical Support for assistance.

There's an extension here that reinstates Design Time stylesheets, most of the functionality is still there in Dreamweaver, just hidden, the last time I checked..... The extension works in the latest version of Dreamweaver.
