Toolbar issue - does not go back to Main

I have this new issue where the left side bar switches to the curve toolbar but never reverts to the Main toolbar. Latest WIP

I have not been able to recreate this problem.

What are the exact steps being taken to get this?

I just did a test. New file. All I need to do is click the ‘Curve Tools’ tab. The leftside toolbar switches from ‘Main’ to ‘Curve Drawing’ but never gets out of it.

@scottd i believe my rui file with a custom toolbar was messed up. I created a new rui file with just my custom toolbar and it seems to work as expected again now.
