Application is working on Windows but when I run on RedHat10 under Wine 1.1.15. It looses focus and underlying Linux applications to get the keystrokes from the keyboard. Clicking on the application we're trying to run or switching with ALT+TAB doesn't not give it the focus back. The parameters we're running Wine are: Allow the window manager to decorate the windows : OFF Allow the window manager to control the windows: OFF Emulate the Virtual desktop : OFF If we allow the window manager to control the windows, then we don't have the problem. But, then we're having problems with modal forms used in our application. I really appreciate if you guys can advise. Thanks
