What's the limit for USER objects in a system (W2K, XP)? Microsoft says 65535. But i found it is much less than that.

Loading about 500 menus, even from a single resource ID, will reach the limit. Task Manager shows about 4000 USER objects in total. You can also try loading 100 menus and fire up 5 or more instances. Maybe the most you can have is 4.

Any thoughts?
