Desktop Widgets: screenlet not working correctly

[rizlaw]

Gmusicbrowser 1.1.99.0 deb and Git master versions under Ubuntu 20.04LTS.

Desktop Widget "Screenlet" has issues: 1. Mouse-over does not pop up transport buttons. 2. Size adjustment buttons don't work properly and aren't labeled "horz" and "vertical". The "vertical" or second box for size adjustment doesn't work at all as far as I can tell. 3. All of the other widgets, including ones I created under prior version of GMusicbrowser have identical problems. I had to delete gmbrc file and start from scratch to recover after Screenlet widget froze at an overly large size which I never set and could not resize correctly.

Glad to see development has started again. :)
