Does the problem occur:
Every time? Or how often?
yes
On other computers?
yes, to everyone

When does the problem NOT occur?
never

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)

Not sure I never tried in early versions, "courier new" is the only alternative that works right and even that I can tell looked blurry.

Workarounds:
Stay in default font.
