I want to comment that I tested updating to your latest version but I experienced an issue, so I went back to the previous one.
The issue can be seen also in your demo project.
To do so please open MainForm and go to the code in Form_Load.
Then put a stop watch in the first line (
Call SetupVisualStylesFixes(Me)) by pressing F9.
Press F5 to run.
When it stops on that line, press F8 to continue step by step.
If the problem is reproduced successfully there, you'll see that the code flow goes to the line:
Code:
Private Function IOleControl_AddRef(ByRef This As Long) As Long
in VTableHandle module and does not move further by pressing F8 more times. It only resumes by pressing F5, but then lossing the possibility to run step by step.
