Summary: Dropped mouse movement in Half-Life/Counter-Strike with
                    Steam or another Win app
           Product: Wine
           Version: 20031212
          Platform: PC
               URL: http://steampowered.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: wine-misc
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When playing Half-Life/Counter-Strike 1.6 with Steam, the sensitivity changes
all the time making it hard to aim.

Steps to reproduce:
1) Get CS 1.6 running with Steam OR get CS 1.5 plus another app running.
2) Make sure mouse acceleration is disabled.
3) Feel the sensitivity change depending on the viewing direction (probably CPU
load) or measure if necessary.
4) Kill Steam.exe or the other app.
5) See that the sensitivity is now constant. No dropped mouse movement.

I don't know Wine good enough (yet) to guess what the cause of the problem is
but developers probably do.

I realise that this bug isn't important to most developers but many users that
play a Half-Life mod (and probably other games that need more than one
executable running) would really like a fix.
