yes minimizing works flawless when i use the button in the program and when i use the taskbar button menu
the problem only occurs using !minimizewindows
and not only for tvgenial but for a few other programs too

with 2 or more affected programs the second program window is position ed just next to the first one (right of it) like a taskbar

tvgenial has an unusual taskbar-rightclick-menu
it show Restore/Minimize/Close instead of Restore/Move/Size/Minimize/Maximixe/Close
i guess they other affected programs have that too
could have something to do with that i guess
