CtxHideEx32 tool has been updated to the version 1.1 and can be downloaded from Citrix support. It now allows a substring search for a window title or class, for example:
CtxHideEx32.exe HIDE "*error" "" OK
As by-product coupled with an optional command line I discovered that it allows to automatically dump any process displaying a message box with an error message in its window title. Here is an example using TestDefaultDebugger64 to simulate an application fault message where the following instance of CtxHideEx32 was setup to dump a process showing WER dialog on Vista:
CtxHideEx32.exe NONE "*Microsoft Windows" "" "C:\kktools\userdump8.1\x64\userdump.exe %d"
We click on a big lightning button:

and then WER dialog appears:

Immediately CtxHideEx32 kicks in and starts dumping the owner process incessantly so you better to dismiss this dialog by choosing something:

We see it was WerFault.exe.
Note: I think I have to amend CtxHideEx32 to make it wait until the spawned command line interpreter finishes its job. Stay tuned.
