Color Panel isn't Showing (TVPAINT12)

[yalih]

sometimes I load the software and its there. and sometimes it isn't.
only when I switch to a different room it reappears.

On windows I experience also sometimes panels missing. When I minimize to desktop (windows key + D) and tab back to tvpaint again those panels reappear again. Seamed they gort sorted wrongly or something. Maybe this will help?
