Summary: ravenshield fails with assertion related to
                    GetClassInfoEx
           Product: Wine
           Version: 0.9.39.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When i run rainbowsix ravenshield, i get the following assertion:

OS: Windows 2000 5.0 (Build: 2195)
CPU: AuthenticAMD PentiumPro-class processor @ 1838 MHz with 1011MB RAM
Video: No Video

Assertion failed: GetClassInfoExW( NULL, WinBaseClass, &Cls
 ) [File:.\Window.cpp] [Line: 1043]

History: WControl::RegisterWindowClass <- UWindowManager::UWindowManager <- 
InitWindowing

I tried writing a small app that creates a class and then tried to 
getclassinfoex on it, but it didnt work either, so maybe getclassinfoex is 
broken
