I use Guides all the time, never had a crash with that particular feature. Wondering what is going awry. The link 'these' leads to a blank page.
Which exact version number do you use, as mentioned under Help, About Captivate. There are several CP2019 versions...
Yeah, I use them all the time too. This was the first time this happened. I'm using version 184.108.40.2066. I finally got it to work by clearing all of the guides I previously had set already. It was kind of a hassle since I had set those when I first started this project and now I had to remember where did I originally set them.
I had tried everything including rebooting and logging off and on from Captivate. I'm not sure why the link didn't paste correctly the first time. This is what I also tried: https://helpx.adobe.com/captivate/kb/captivate-crash-launch-perform-action.html
Thanx for your help
Clearing the cache is not included in that KB, can sometimes help as well.
Since you like Rulers and Guides. I really want to be able to save a grid set up with each project or Theme. That is not possible yet, logged feature requests but looking out for other users who do use Guides as well to log a similar request.
If you are on version 220.127.116.116 then you might also consider updating the app. At this moment the most recent version is 18.104.22.1689.
