Big Fireworks Problem- Anyone else have this?

[laxplaya1346]

So I try Fireworks on Safari on my Mac computer and as expected it just boots me back to the lobby. So i log on firefox and try to play. It works and is not slow but sometimes when i click on fireworks they will explode and sometimes they won't (I'm clicking them at the end when they are good,or awesome). The only thing that seems to work for sure is the Space Bar and that's no help. Then after i get my minimum credits (recently 17) I am in the lobby and can't click anything! I have ot log out and log back in! Boy macs are a pain.....
