I have a toolbar with 2 togglebuttons. I have a program written in C# and another in VC++.NET of the same code. In the C# program, the toggle button would pop when the other is pushed and vice versa. In the VC++.NET program, this doesn't happen. Both buttons could be in the pushed state. Is this a bug?

A workaround is to write code to unpush all the toggle buttons when one is pushed.
