According to the Wiki, Frames can receive a Click event, and if so should react to such under the SUB __UI_Click subroutine. I did try this for a Frame I wanted to react to at run time. However, a Click had no effect (and the code did not pass through the CASE Framename region). For my case, it doesn't matter as I changed it to clicking on a Label in the Frame. That works very nicely. Richard
