changePage results in blank page
I'm working on a multipage site using jQuery Mobile 1.2.0. When I call $.mobile.changePage() I end up getting the proper hash, but the page is blank. Refreshing the page gets the page to show just fine. I found a post on here mentioning that custom CSS may be the cause of the issue, and I have tested without my custom CSS and things worked just fine. However the custom CSS I'm using came from the jQuery Mobile Themeroller, so it being wrong is kind of odd. Regardless, I compared the CSS and I am unable to find any real differences other than the color codes being used. Does anyone have any ideas as to where in the CSS I might find my issue, or what else to look into?
