Hi,

I have a WPF application and a worker thread. The worker thread invokes a callback on the UI thread, which opens a new dialog. Works fine on Win7, but on XP it will crash.

In worker thread:

someWpfDialogInstance.Dispatcher.BeginInvoke(openSomeDialogCallback, null);

Does someone knows a solution or a workaround for this problem?
