Strange behavior when using two CEP panels simultaneously

Hi there, at my workplace, we need to use two CEP panels at the same time. One of the two panels was developed by me, the other was delivered to us as is and we have no control over it. Basically, both panels perform fairly basic operations; opening and closing projects, renaming sequences, locating videos, etc.

But I feel that when both panels try to interact with Premiere simultaneously, I get bugs and they don't work properly (project won't open, panel stops responding, etc.).

I understand that there is only one ExtendScript engine shared by all extensions, but is there a way to prevent the two panels from interfering with each other? For example, by making my panel wait for the other panel to finish its actions before performing its own.

I searched the documentation and the forum but couldn't find a solution.

Thanks
