I am developing a project for Microsoft Office 2007, using Visual Studio Tools for Office. I am making some WPF UserControls that I am displaying in the application.
When I do ShowDialog(), the entire application freezes. I tried seeking help on the Microsoft forums, but recently I discovered that this happens only when I use control from the ActiPro dlls.
Here are more details regarding the problem on the MSDN forum: http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/815a36ef-68f1-4095-ad17-0630d138c17f .
Can you tell me what is the cause of the problem?
