The desktop software's dialogs are unusable with my multi-monitor set-up.

I eventually found a work around by accessing my computer using RDP when I set up for this year's returns. That way, you appear to be only on one monitor.

Then I went back to normal 3 monitor operation to enter the tax data. Ugly procedure but it worked. The font problem still exists but it is not as painful after you get the returns stsrated.
