Rich & Martin,
Query os2.ini->PM_SystemFonts->WindowText to get the font name & size, then use it.
Which specific lswitch282.ini key are we talking about here?
I see the following:
1) TitleFont
2) ButtonFont (which I suspect is the TaskBar button)
3) HintsFont
...haven't tried any of them yet as none seem to imply the PopUp font control, which is what I'm interested in changing (b/c the TaskBar seems to be just fine).
