Hi,

I hit an odd point where the page up/down, and cursor keys stopped working.
Oh, I couldn't do control+O (open file) either.

I could scroll up and down by the scroll bar and mouse.
I could type letters.
I could switch to Outlook and do all of the above (i.e. the keyboard was working).

I could save my files and close EmEdit.
Upon reloading EmEdit it seemed fine again.

I checked to make sure I wasn't recording a macro (I'd run into that with other text editors).

I'm not really sure what lead up to this happening.
