dizzy updated his thumbnail fix to the new patch.
Unfortunately, he hasn't updated it for the new patched no-cd.
This means that you have to run his fix every time that you run the game.
"If you have the patch, you will need "thumb2" which you must run *after* you load Sims 2. This patches the game while it's running, so you'll need to do this any time you restart the game. (Not ideal, but the best I can do right now.)"
