I know I can position the switchbar at the top, bottom, left, or right of the main mIRC window by mouse, but how to position it by script?

Search is the best place to start...

Click here and type:
Words to Search For: Switch bar position
Search Options: AND
Date Range: All Posts

then hit SUBMIT

To save you time, here's one I found in the search: HERE

Thank you!!!!!
