P: Can not exit/switch Full Screen Preview (F Key) mode (LR Mac)

I've been a few days now - without the problem reoccurring - so deleting the Prefs file - seems to be a workable cure.

Please find my posting earlier in this thread and try the suggestion of using keystrokes to perform the full-screen menu command instead of the F key. Also, try the suggestion to use a mouse to open the Window menu and click a Full Screen option.

Hmmm, it seems, that nobody is aware of this problem. It seems, that nobody works on it.

After upgrading to 10.9.3 the problem returns - unfixable.

It is absolutely annoying. Since I'm using LR as catalog and viewer, it seems, that I should have a look at Aperture, Capture One, or other related software.

This is a problem Adobe is aware of and hopefully will have a fix for in their next update. Not sure there is anything you can do besides not use full screen mode until the next update is released.

Deleting Cache - no effect
Deleting Prefs Files - seems to have cured it for now

Same problem - started happening tonight. Doesn't matter which mode it's in. If you go to Full Screen - F key - it won't exit it. This is on an iMac, 10.9.2 LR5.4 latest version.

Press F - goes to full screen. Press escape, G, E, D, F - it returns to normal, but then bounces immediately back to Full Screen.

Really annoying. Haven't found a way around it yet - and am just about to attempt any fixes suggested above.

On Mac my workaround is to use the Speakable Items feature in Accessibility preferences, in System Preferences, to create a Speech Command.

The command I created uses the Listening Word "Computer" before each command.
In the Commands tab, I enabled (checked) only Application Specific Items, and Menu Bar. This makes speech commands only respond when you're in LR.

So, to exit Full Screen Mode, I say: "Computer, Window Menu, Computer, Screen Mode, Computer, Normal."

For specific help, highlight Speakable Items in the Accessibility control panel, click Commands, then click the "?" to bring up the Help Center. If this is your first time setting up speech commands, it will take a few trial-and-error cycles until you get it right. One tip: remember to make LR the active application when speaking the command. It's easy to leave the System Preferences panel active when you're working with the Accessibility settings, so don't forget to switch back to LR to give the command.

HTH

If anyone knows where to report LR bugs, please submit this workaround there.

UPDATE!!! After I set up the speech command and used it a few times, just for fun, I tried tapping Escape to exit Full Screen and IT WORKED! I tried it a few more times successfully. Then I disabled Speech Commands and went into full screen and exited with Escape. Apparently executing the command by speech fixed something. I quit LR and restarted, and Escape still exits full screen. I haven't tried restarting the Mac to see if the fix persists.

Started happening here. LR hung, so I force quit it. Now it keeps bouncing back into F mode even after I hit escape. I'm on Lightroom 5,4 Mac OS X 10,9,2.

Ugh.

Brilliant! I just searched the web this evening for a solution and this worked for me too. Thanks!

Quit LR and press SHIFT+F after re-opening LR. --- OK thanks
