When you right-click the desktop and then click Properties, the pointer may change to an hourglass for 2 to 3 seconds, and then nothing else may happen. The same behavior may occur when you attempt to start the Display tool in Control Panel.
An entry that is placed in the registry by the software for your video adapter may prevent Display properties from being displayed.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
There may be several keys under the PropertySheetHandlers key. The two standard keys are DeskHtmlExt and PlusPack CPL Extension. There may be a third or fourth entry with the name of the video adapter.
For each key other than the two standard keys, follow these steps:
Click the registry key, and then click Export Registry File on the Registry menu.
Type a name that will help you remember the name of the key, and then click Save.
Delete the key by pressing DELETE.
Repeat steps A through C for each key other than the two standard keys.
