clues to cache-like behavior

Hello, I took some PHP/MySQL code that seemed to be working fine from a LAMP setup and brought it to a MAMP (mac OS) setup. Now I am seeing a cache-like behavior in my admin forms, where my last changes don't "stick". To be clearer, I go to make a database change in the forms I built to administer the MySQL db, hit submit, then check the results on the public side. All is fine at this point. The changes are there. However, I decide to adjust something and go to make another edit, however, my admin form shows the prior data.. not the last edits. Checking via command-line the edits are there, and if in and out of the edit page a few times, the last edits finally appear. Anyway, I've only built a couple MySQL driven sites so far, and haven't gotten all the way through my O'reilly MySQL book yet, but I thought I'd see if this kind of thing rang a bell with anyone. If I had to make a blind guess, I'd guess a config issue (either PHP or MySQL), as I don't remember this behavior in the LAMP setup. TIA for your comments. Donovan -- D Brooke
