There are almost no settings for this in Maximizer so I would double check the configuration in Windows. Possibly the change may have resulted from a Windows update but not aware of this problem being previously reported. If you are using Windows 7 it is possible better compatibility might be obtained by updating to the latest version of Maximizer(12. However, I would not wish to suggest that this is a guaranteed solution to this problem.
