well, i'm using 1024 x 768 display with no problems. the min form size is set to 800 x 600 so if you're using a resolution that is larger than that, then you should be able to see the entire form. if you're not, the only thing i can think of is perhaps you're using some sort of oversized fonts or strange theme that blows up normal window bars and other screen real estate by using large fonts and icons. if that's not the case, then you should check your settings.ini file and look at the following lines:
fHeight = 600
fWidth = 800
if those values are larger than your screen size, then you should change them to the above values or as a last resort you should BACKUP
your settings.ini file in the RMTM dir, delete it, and restart RMTM. if that still doesn't fix it... then i'm kinda out of ideas.
