I believe I found the answer to my own question:
The default LabVIEW Application Font depends on the Display settings on a
user's particular machine. The font used is the same font assigned to the
"Icon" item, as shown in the "Display" properties for the machine. (Go to
Control Panel and choose Display. Then look at the Appearance Tab, and
choose the item "Icon". You'll see which font and font size are being used
for "Icon".)
