Isometric game

[mrownage]

Hey everyone I'm currently makeing a Isometric game much like Diablo only less good :P However im having some problems getting it off the ground, I can move my player up, down, left, right but when I try diaginal movement he moves but doesnt change animationto the right one he stays at the one he was at and then travils. The other issue im having is lag, I can move my level around and it stops where I want it but when moving the whole game lags up. My level is only slightly bigger then a normal screen, but iv seen much bigger games run perfectly! Does it get better once published? Or are they doing somthing im not? Please help me if you can ;)

Thanks a bunch I look forward to hearing your replys

First off, I assume you're using AS2 not AS3?
Second, the tiles in your game, are they vector or bitmap?
Are you doing anything like removing the tiles when they are off-screen?

Im not sure about AS2 or AS3 but no im not removing tiles when there off screen (dont know how) but if i found out that would be great.
