Obviously I haven't explained very well. The default font sizes are
different in Windows (8) and Linux (10), but as long as I stay in the
same OS and don't alter them myself, they don't change. I suppose my
general system settings are responsible for the difference in the first
place. But some buttons were just right on Windows, and on Linux they
are too small for their captions. Fiddling with the expand settings
often helps: with sizer_expand checked or the proportion set to 1 the
button is big enough for its caption, and if I change back those
settings, the button shrinks not to its old size, but to a new one which
is just right for the bigger font. Only with one button this doesn't
work, it always changes back to its former size (right for Windows, too
small for Linux).

Ok, I'm using the text color for this. As long as I know about it ...

No, the border is completely in the wrong place: all of it is under the
text and not around it.

Sounds complicated. I will think about this, but first I'll get the
application to run.
Thank you,
