I keep my taskbar on the right side of my screen, usually with auto-hide on, and I've noticed that after a while (maybe a day or two?) the taskbar becomes narrow. I really like it narrow like this. It's just barely wide enough to show the time, not wide enough to show the date, and the orb is just a little wider than the bar itself. I think it looks great, but I can't figure out how it got that way. If I play with the size of it at all by dragging the width then it will revert back to the 'wide' version despite my attempts to drag it back to the narrow version. Then after some time it will randomly become narrow again. I'm using the RTM version, by the way.
