The game 'Mafia' when run in the same Windows session as Boinc causes a fatal Visual C++ error when 'Show Graphics' is clicked on. The error is 'can not find path' but I don't think that is relevant. This error also occurs with the SETI graphics. I have begun to turn off Boinc when running any game and restarting Windows when done with the game. Some game evidently do something to Windows or the Visual C++ system or the DirectX system.

This is running on WindowsXP Home SP1 on a P4e with HT enabled.
