Still having trouble, and the same thing is happening with this workbook on two different computers, so I don't think it's a hardware, or OS specific issue.

The only way I've been able to get back to normal is by force closing excel altogether and re-opening. If I go into the VBE, I can manually run procedures and they all work fine.

I've made sure that screenupdating is turned back on at the end of every procedure. I can't think of anything in my macro that would have these kinds of effects. I don't understand what's going on at all. So if I press "s' it will input "ss" into the cell, and then when I press enter it will auto-move to the next cell down, but nothing ends up getting saved into the previous cell. Then it gets really strange - when I have a cell highlighted and press any key to input text, it gets duplicated. BUT, if I use the keyboard arrow keys, I can see that the active cell selection moves accordingly. When I click anywhere (trying to select a cell, or an excel menu item.clicking anywhere in excel) I'll get the a 'ding' system sound and nothing will happen. Occasionally it will run as expected but as soon as the macro ends, excel becomes unresponsive to mouse-clicks. I have a fairly lengthy macro that works perfectly most of the time.

I've been having a strange problem lately. Posted this on the Ozgrid forums, but haven't gotten any help yet, so I thought I'd try here too!
