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.

Did you assign many shortcuts? Are you using the Registry (Installer) or INI files (Portable version)? You might want to go to Properties for All Configuration on the Tools menu, the Keyboard tab of configuration properties, and press Reset button. I hope this helps.
