Since Upgrading Screens appear blank, but reappear on re-loads

Like the subject line says, since I upgraded to 3.2.1 this summer I have had the strangest problem.

When I go to a page, either on the blog or on the back end control panels, the URL will load completely and the page will be a blank white page. If I hit the reload button it comes right up, normally.

I have confirmed this on multiple computers/OSs, and browsers.

HELP???

BTW: It is NOT an "always" thing. It IS on the home page and on the control panel's home page, but it is hit/miss on other pages.

THANKS!

What version of Atahualpa are you running? If 3.6.7 do you have the patches installed?

One other thing I noticed is you header image are quite large at about 340Kb. You should be able to easily get these below 100Kb. Those file sizes lead to slow page loads and may have some part of your problem. You might also try deactivating your plugins to see if one of those is the culprit.
