I'm having an issue with the tabsets for my open windows.
I create tabsets for the windows I need to keep open, and save them, but they seem to reset at random. Some days everything works as expected, then out of the blue they're gone and I have to recreate them.
I'm opening them through the Catalog using:
::tabset("load", "PROJECT TABS")
and then selecting Go to Location.
I've tried this a number of times and the same thing keeps happening. It'll work fine for a couple of days, then one tabset won't open the correct windows, and before long another one does the same.

I've also tried saving them under different names and locking the windows, but it doesn't seem to make any difference.
Is this something you've come across before, or is there anything else I should be trying?

Are you using multiple instances?
You are aware that there is a toolbar button to open tabsets, which presents you with a list of all available ones.

I'm using tabsets all the time and switch between them several times a day and never had one "disappear".
