Plays Smooth In Flash / Lags In Browser

1

When I view my site in a browser, it’s just choppy enough to annoy me. My site consists of four sections, each are separate .swf’s, under 130K, preloaded, and are set to 30 fps. The two parts that I find most noticeably choppy are when a small, all-white box quickly expands to a larger box and then fades away to reveal a fairly large (600x420) bitmap background. It seems that I’ve seen much more intensive sites without noticeable choppiness. Like I said it’s not awful, but it’s just enough to bug me – so I am looking for a solution. Any suggestions would greatly be appreciated. Thanks!
