I am working with Asp.Net for the last four years and I never experienced this kind of issue..
I have finished a big project recently and while testing we found some serious issues.. when I put debug and step through the code I can see sometimes the Page_Load is happeneing multiple times. This is happening especially when using Firefox. IE also causing this behavior sometimes but lot less compared to Forefox.
