But if I type anything else (numbers, letters, or symbols) then it types 2 instances of the key every time, yet when I hit enter, nothing changes in the cell. If I use the delete key to delete the contents of a cell, then it gets deleted. If I'm in the excel window, I can click alt on the keyboard and the shortcut keys for the menu come up, but I can't go deeper than that by clicking the letter shortcuts, they do nothing. When it gets locked up like this, I can still do anything in the VBE (edits cells, run macros, etc.) with no problems.
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!
