Hi,

It also leads to minor graphics glitches (the frame borders around the
windows are sometimes not redrawn correctly), but I greatly prefer this
over editor windows without visible text ;-)

I also doubt that the problem is about _physical_ memory. But maybe it
has something to do with the amount of memory that the graphics driver
allocates for doing its stuff (and just as a background information,
driver programming is almost as obscure to me as understanding women, so
I am probably completely wrong about this). My main point was just that
two monitors seem not to be a requirement for reproducing the bug.

This is interesting to know; thank you.

Best regards,
