How to access start menu preferences

[MogyBear]

I recently changed my preferences so that subfolders would appear instantly when I move my mouse over them. I would like to change it back, however. The problem is that I can't remember how I changed it in the first place! I thought for sure it was in TweakUI, but after looking again, I can't seem to find it. Any help would be much appreciated! Thanks.

On Win98SE it is: Start > Settings > Taskbar & Start Menu...
