I'd say it's confusing the DLL initialization sequence, as the function
doesn't even have to be called (see the simple hanging example in this

Speaking of which, what's the version of SHLWAPI that hangs? On my
machine (which doesn't exhibit the hang) I have
$ ls -l shlwapi.dll msvcrt.dll
-rwxrwxr-x+ 1 Administ SYSTEM 300816 Oct 20 2000 shlwapi.dll
-rwxrwxr-x+ 1 Administ SYSTEM 290869 Oct 30 2001 msvcrt.dll
The properties dialogs show the following versions:
File version: 5.50.4522.1800

File version: 6.1.9359.0

I don't know if it'll help, but it might be worth a shot...
