Userform - Transition effect

[JSA715]

I am having problems with the transition effect on a multipage. It seems to only work on one setting (cover right up) and only at one speed no matter what I set the period to. If I change the effect, then the page will flicker. It appears it MAY be doing the effect, but just at a VERY high rate of speed. It's difficult to tell as my brain has yet to adapt to processing items in nanoseconds.

Any Ideas on this? :help
