No. The Windows task bar. Just to the right of the Start button.

The system tray is on the right-hand side of the task bar and I have mIrc configured to not put its icon in the system tray.

Animate icon when there is activity is de-selected.

I did.

Not to my knowledge. I certainly didn't write one. Where would I check that? In the scripts editor I checked the aliases and popups tab and don't see any reference to /flash. Remote, Users and variables tabs are all empty.

BTW this is Win 2000.
