Is this a Cache problem?

Ok, I’m having a weird problem with my ICT Coursework. (Flash Web Design) The site works fine when I run it on my computer, but when I put it up on the web, it stopped working. After a bit of experimenting I foiund that a refresh after it’s given a “A script is causing the flash player to run slowly” message will open it properly. I have a feeling it’s something to do with cacheing my dynamically loaded stuff. (xml, pictures)

Anyone know what’s going on?
