it is off the screen to the left?
If you hadn't uninstalled and re-installed I would have suggested an unusual option to try, but re-installing should have made that option unnecessary.
But anyway, the suggestion is this;
Have you, or anyone else who uses the computer, set Windows up in two screen mode?
If you have two screens you will know what I mean. Windows will display on both screens and you can drag from one screen to the other. But what makes it interesting is if you drag an application over to one screen, then turn that screen off. Then although it is visible in the task bar, you can't see it on the remaining screen.
Have a look at Display Properties, (just in case). Right click any empty part of the Desktop, select Properties, then the Settings tab, and see if both monitors, (1 and 2), are highlighted.
If so, highlight monitor 2, and take the tick out of the ''Extend my Windows desktop onto this monitor'' option.
BEWARE, this is the right hand monitor, but as you say that DivX has disappeared to the left, if you de-select the wrong one, you may not have a display to work on.
I went to open the Divx Player and I could see the icon in the toolbar and hear the audio, but I can't see the actual player or video(it is off the screen to the left). I did an uninstall-reinstall, but it didn't help. Anyone know what the problem is or how to fix it. Thanks.
