Transparent palettes with 6.0.2 on Linux

[Richmond]

Just now I had a "funny thing": editing
my SCHEDULER stack which I use for
timetabling my EFL school I tried to
close the stack prefs palette and it
turned into a transparent shadow
of its former self. Subsequently,
trying to open the prefs palette for
a textField I ended up with the same
'ghost' of a prefs palette.

That's on Linux: I wonder if the same thing
is happening on Windows and Mac?

Don't have time to find out just now, but will try to
find time tomorrow.
