------- Additional Comments From Speeddymon@gmail.com 2005-14-05 13:41 ------- you can try running the installer in desktop mode, or changing the dxgrab option (if it exists in your wine config file). Also check the wine registry for related options to keyboard/mouse grabbing.
If neither of those work, please post the last known version of wine that the installer worked properly on, if known. If you don't know, let us know that too, so we can have you try different versions to see if it ever did work.
