Last one I promise...

Again, in AutoCAD 2000. This one is a bit harder to explain. When I use the undo command, normally the screen zooms back to wherever the undo is happening. But now, when I undo, the screen stays zoomed into wherever it is when I enter the command and I have to rely on looking at the command line to tell me which commands are getting undone instead of watching them get undone. Is there a setting I can change for this??

Thanks!
