Hi!
I am using the .NET 4.0 version of Winforms edition for some years.
After upgrading to Visual Studio 2019 I am no longer able to use the designer for a C1DockingTab.
The designer opens and I can select the C1DockingTab but I cannot change tabs to make changes on other tabs but the first.
I am able to reproduce this with the RenamingTabs-Example.
Here are some screenshots to show the consistent usage of the same version.


I tried to apply the tips from https://www.grapecity.com/forums/winforms-edition/unable-to-open-in-design-m#hiin-order-to-resolve-the- but to no avail.
What else can I try to use the designer properly?
Thanks, Markus
