I checked the cvs logs, there have not been any changes to the popup menu object. I
have also check for changes in other core files (i.e. Fl_x.cxx, etc. ) and there
have not been any changes that should effect the popup menus. Are you using the
Nano-X windows manager (nanowm)? I've noticed that it will put a title bar and
border around menu bars and popups. Flnx was setting all new objects to the root
window, even if it had a parent. I have fixed this behavior and will put it into
cvs after I have tested it more. To see what I mean, run flnx/tests/tile: you'll
see that the child window is positioned in the wrong place (because it thinks its
parent is the root window). Even though this fixes some of the issues with nanowm,
it still will put titles and borders around many items. This is something I'll have
to look into... What I think is happening is that the nanowm will put a window
around anthing that has a window id (even if it has a parent window).

True type fonts will fix this problem. Another way to try is to edit fl_fonts.cxx
and then recompile.
In fl_fonts.cxx you'll find this:

What you want to do is comment out the top part and use the bottom part. Then
recompile (You'll have to get rid of the macros too, of course). So basically
you'll end up with something like this:

Can you give me some more details? How does it misalign? If you're using the
default font, the text is misaligned vertically on everything (i.e. buttons, etc.).
Try changing the font (use true type, for example) and see if that fixes it.
Thanks!
