Exception when opening a form using WPF ShowDialog

Question

I have a WPF application when trying to open a form using ShowDialog() , I get this strange exception below on one machine.
Any idea what could be the problem?

Exception message = operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT)) Trace exception stack =

I got the same error and the problem is with the Font Cache Service Windows Presentation Foundation. His cache file is somehow corrupted. Following the instructions in this MS KB article, http://support.microsoft.com/kb/937135 , I was able to solve the problem.

This applies to both Cache 3.0.0 and 4.0.0.0.

Before I found this article, I just stopped and disabled the service, and my WPF application started working. I suspect that disabling this will slow down the display of WPF applications (which is already quite slow), but after several machines have this issus in the field, I turned it off and have not had any problems since.
