UI Thread deadlock

After updating a customer to a newer version of our software, the ui-thread
locks after one or two hours of running the application. We already installed
this version on about 100 systems but this one is the first having this
trouble.

I already set the "Control.CheckForIllegalCrossThreadCalls" property to
"true" in the hope it was my failure, but i do not get any exception, the
thread just blocks.
To get a bit further I installed Visual Studio 2005 on one of the customers
machines and could get a callstack (added at the end of the post) out. But
now I am in Framework-classes and do not know how to find the problem. Is
there any tool which can tell me for what handle the framework-class is
waiting?

Windows XP SP3
..NET-Framework 2.0 Service Pack (+ german language pack)
Compiled with Visual Studio 2005

Appretiate any hints.
