If that doesn't happen, random plots tend to scrawl all over the widget instead of going to a normal graphics window. Obviously I could use WSET, TVLCT etc on the command line if necessary, or just remember to click on the widget if I happen to run the cursor over it, but that's clunky and shouldn't
be necessary (and isn't, under linux).

I would write a "draw" procedure for each of your widget windows. When
you want to draw graphics in that window it first saves the current
graphics state, makes itself the current graphics window, draws its
content, then restores the graphics state it entered with. Simple,
compact, leaves no mess, and works everywhere. :-)

Cheers,

David
