> I was wondering that as well, so I had tested with repositioning built-in and other add-in toolbars to see if crash-on-exit killed prevented them from being persisted, and those layout changes for non-Rubberduck toolbars still do get persisted, regardless of the crash, unlike Rubberduck.
Do you have your own toolbar positioning persistence code or registry entries? If so, it seems likely would be tear-down / crash-on-exit related, but I suppose even if not it could be related to that.
