Desktop very large after crash - how to fix it

[jnklm]

I was copying a cdg with microstudio v2.200 and it was about 2 song into it when it crashed and went back to the desktop. the problem is that the desktop is very large now and it is so big that i cannot change it back because i cant see the box in properties to change the screen size back to normal. anyone have any ideas on how to fix this because at this point the computer is useless, it tried rebooting and that didn't work and i'm using another computer to write this.
