I don't know how this happened, I'm usually pretty good about this kind of stuff but here's the problem, don't know how to fix it:
I click Start > All Programs
and all of my programs in the list are there, but for some reason I can no longer move them around. I used to be able to hold down and drag them to different positions, but now I cannot. I also cannot right click in the all programs menu (the same options come up after right clicking the taskbar which CAN be right-clicked). It seems the all progams menu is somehow 'locked'. I have tried unlocking the taskbar but this does not help. Any suggestions?
