Edit: Nevermind. I don't know why it suddenly wanted to do it, but I was able to drag it over (along with all of my desktop icons, which is annoying, but whatever). It may have been because I had too many programs open, and not enough room to grab on empty space in the task bar.
I have two monitors, and in Windows XP, I was able to drag the taskbar between the primary and secondary for when I had full-screen games running on my primary monitor.
But in 7, it seems that the only way to move the taskbar between monitors is by going into Screen Resolution and setting my second monitor to be the primary, but then that defeats the purpose of moving it, because then full screen games load on the screen with the taskbar, and as an additional side effect, it screws with my dual-monitor wallpapers :'(
Is there any way at all to unlock the ability to drag my taskbar around, or at least send my taskbar to Monitor 2? This is really frustrating.
