By no means conclusive as far as being the culprit, but anyone heard of problems with (some) HP printer drivers crashing (access violation, unhandled exception) in apps using xtpro?  Appears to be x64 only.  Thanks.

Yes!
 
If you have the src there appears to be suspicious behaviour with code originating at CXTPSkinManagerApiHook::OnHookLoadLibraryExW() and following call to GetInstance()->HackModuleOnLoad() which in turn does ReplaceInOneModule().  I'm certainly no expert, but the term "code injection" was being mentioned here as possibly something that causes problems in the injected dll downstream.
 
No sure in any of that makes sense, but hanks a lot for you reply.

For future reference adding HPCUI081.DLL to the ExcludeModule list appears to workaround the problem.  Hopefully HP will still work on it to bombproof their code.
