I've been using AnyDVD & CloneDVD for years, both on XP Pro & Vista Ultimate, without a problem. I downloaded CloneDVD Mobile to give it a try but when I got to selecting the video file I constantly got the message "CloneDVD mobile Application has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." I trawled through this forum & tried everything suggested, including the tabtip.exe & asghost.exe solutions, without success. I've been using Windows Sidebar which comes with Vista. Through a process of elimination I found that if I close Windows Sidebar I don't get the error message and CloneDVD Mobile works perfectly. When I restart Windows Sidebar again, & try to use CloneDVD Mobile, up pops the error message again. I hope this may help some of you Vista users having similar issues. Just try temporarily closing Windows Sidebar while you use CloneDVD Mobile.
