I used to devellop using xampp & IE8 (one tab running my application in and another tab running phpmydamin in).
Using this setup i ran into trouble running scripts with MYSQL UPDATE functions in it. the UPDATES were either not executed or just some of them executed, in lucky cases sometimes all were executed. on every new reload the UPDATE behaved differently.
yesterday i ran a script with two UPDATEs in it. on the first reload it would only execute the one update, on the second update the other one was executed and so on, in lucky cases both were executed ...
My soulution for now is to use another browser (for instance Chrome) instead of IE. then everything works just fine. the only way to make it work in IE is to close the second tab with phpadmin running in it!
Has anybody ever heard of that problem or has an idea what the reason for this might be???
