9. The four windows of MAXQDA are not displayed correctly anymore.

It sounds like the file containing your user settings might be corrupted. Please reset your user settings through the windows start menu: “Start” > “All Programs” > “MAXQDA10″ > “Tools” > “Reset user settings”.
Please be aware that due to this your list of recently opened projects will be emptied. Your MAXQDA project files remain untouched at the location they were saved at and can be opened through “Open existing project” > “other project” > “OK”.
