Hopefully someone has a clue....
My application displays WPF Window as a modal dialog box. The dialog box has a few child user controls, one of which has combo box. When the user clicks this combo box to select... the whole dialog disappears except of the innards of the combo box. So the
user only sees the list box of the combo box.
Here are the details I got from the client: The window itself is launched from non WPF application (Lotus Notes). This happens only on a few machines. The OS is Windows XP SP3. There is no issue with the parent handle, windows owner, etc...
I've seen this behavior during the development phase, only when running under a debugger.
