Good question. No I can't. Now the problem has stopped happening in my normal config.
It seems kind of related to the macro I wrote here
https://community.slickedit.com/index.php/topic,16659.0.htmlhowever there isn't any code there that knows when the cursor is about to disappear off the screen. I believe I was using the normal fast-scroll for wheel-up/down when I had the problem, I switched to my alternate version of fast-scroll then back to fast-scroll - and at some point the problem went away. At some point I'll investigate this some more.
