Trigger panel freezing while working in Storyline

Hi everyone,

This last week, I've been experiencing a very strange problem while working in Storyline. About 10-15 minutes into working on a project file, the trigger panel will suddenly freeze. Once it's frozen on a single slide, it doesn't matter which slide I click on, the trigger panel won't change. As such, I can no longer edit triggers. As someone who works in Storyline for hours a day, it has been a pretty big problem! The only thing that solves it is exiting out of the file, then restarting my computer and reopening the file. But even then, the file will only work for some time before the problem starts again. 

So far I have tried the following: 

• Downloading the latest update 
• Uninstalling and reinstalling Storyline 
• Importing the slides into a new project file (unfortunately, it's happening in all my project files, not just one) 

I have also contacted Storyline support but so far they have been unable to solve the issue. As such, I thought I'd post it here and see if anyone else had a similar issue or ideas for fixes. 

Thanks,

Allyson
