I'm totally impatient too!! it gets in the way of my projects ALL the time.
Hm thats weird... i would guess probably something to do with the humidity. I haven't had a problem with my pages sticking together.
here's an exerpt from this website: http://stampinmama.typepad.com/stampin_mama_a_mama_that_/2006/07/our_love_affair.html
"Are you having a problems with the acrylic painted pages sticking together. If so, a couple of things you can do - get some Dorland's wax and rub it over the pages then buff with a soft cloth. Or dust the pages with Pearlex. Not only will the pages shimmer, but the dust will help to keep the pages from sticking. Or tip-in a pretty piece of tissue paper between the pages. Just some ideas . . ."
hopefully that will help!
