I find a problem with newest version of your plugin, Delphi 12 and newest TMS VCL UI Pack 13.0.5.0
I have a demo project with 3 TMS components and when i want to copy this components, Delphi occurs a exception.
When i want to close the unit, Delphi occurs a exception.
This happens only with forms which have a AdvOfficePager component.
When i deinstall your plugin, it don't occurs.
When i install it again, it occurs.
I already send stacktrace to TMS, they say that problem don't happen without your plugin, so it is the problem of TMS.
They can investigate time but i have to pay.
Can you take a look, if you can find something with TMS components (maybe try the demo) or if you can find something in your plugin?
If you need more informations, let me know
