fixed header jump

fixed header jump

Problem: The fixed header jumps about 1/3rd down the page when transitioning, then pops back into the right place.

This is on JQM 1.2 or 1.3 ... This is happening in the browser, before I've even compiled for a device

This happens only when using the Slide transition ... not on the default transition.  Well, it may happen on other transitions too, but I only tried the default and Slide.

I've seen references to this elsewhere, but not a solution that works or has described this specifically.
