Summary: test case demonstrating PeekMessage give up timeslices
           Product: Wine
           Version: 20050725
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-binary
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hi,

the test case whitch demonstates the differece between Windows   
and wine.

On Windows XP  
- Start 'test.exe' from a dos-box... you see some FAST counting integers  
- Start a other program witch consumes mutch cpu time.  
- the output of 'test.exe' is slower but FAST

On wine  
- Start 'test.exe' from a dos-box... you see some FAST counting integers  
- Start a other program witch consumes mutch cpu time.  
- the output of 'test.exe' is very slow

This different behavior starts from wine version 20041201. The version before   
was ok.

I have no patch and it would be nice if someone can write a patch to fix this.

Thanks

Oliver Mössinger
