Here is the problem I run several windows apps none of which run in Mac OSX but i would still like my main os to be OSX. hence the parallels install. what i have tried to do is specify which spaces individual windows apps run in in spaces but this causes major problems when switching between apps using alt+tab or even the dock. what seem to happen is the when selecting the app it will generally switch to the correct space. however when i focus the app by clicking on it the results will vary from staying there to switching to the last space, or switching to the space parallels was started. has anyone else experienced this problem or found a solution. Thanks. Dale
