At least once a week if not more often, someone posts to the forum about getting unwanted duplicates when moving objects. There seems to be about three different things that have been reported so far to cause this duplication anomaly.
1. You are using a Logitech mouse. Some users have reported that it is the driver that comes with the mouse is the culprit behind the unwanted duplicates.
Fix: Some users have reported that installing the latest driver for their mouse has helped. However, for other users, the best solution has been to remove the installed Logitech software and use the Windows default/generic driver for their particular Logitech mouse. This may affect some of the functions of your mouse.
2. Your Spacebar bar is sticky.
Fix #1: If your keyboard really IS sticky...did you spill something on it? You need to clean it :-).
Fix #2: If you have enabled Windows "sticky keys" accessibility feature, you will need to change the settings or turn it off. Pressing the SHIFT key fives times in succession turns the sticky key function on or off (Windows XP, Vista and Windows 7).
3. You have been running CorelDraw and/or your computer for long periods of time without rebooting. No one is sure why this happens, it could be related to memory (computer or video)...or not cleaning out your Windows temp files. Users with older and newer computers have reported the duplicates issue, but it is too hard to pinpoint the cause.
Fix: Try closing and restarting CorelDraw first. If that does not work, reboot your computer.
4. This problem was supposedly resolved with one of the Service Packs for CDGS X5. Make sure you have installed them installed. Go to Corel's main website to download the latest SP.
