Movie from pc to mac and back..performance hit

[WarMecha]

Me and a friend have been working on a flash file together and so it has been going back and forth between our two machines. I have a pc and he has a mac, and up until the last switch the published movie ran smoothly. I sent a near final version of the file to him for some graphical tweaking, which was running smoothly on my machine, and he commented that it was slow on his. On sending the file back, it is certainly far more sluggish when both previewing and publishing. Nothing has changed in the file that should effect performance and so I am at a loss as to what is causing it? He is working on MacOSX and so flash should be optimised?!? I am running XP. It is not really practical to revert back to an older file at my end and make the changes myself. Any ideas on what might be causing this, it is almost like the frame rate has been lowered, but it has not?

Thnks for any help anyone can offer

I don't know why this happens, but usually the same flash files run slowly on a Mac than PC, even in the fastest mac...

I haven't found a solution for this yet, I work on both PC & Mac.

So if anyone else has notice this and have a solution.

By now I think that there is no way to solve this, just have to live with it.

Your probably right, not something that can be solved perhaps. Just seems a bit wierd that bringing a file that has been modified on a mac should be brought back to pc and be permantently slower in performance even though it is now again on a pc. I would like to think that this is something Macromedia is working on, but who knows? The bottom line is, something must have been changed in the flash file, and seemingly something that is out of the users control. This must be a problem that can be adressed therefore, lets hope an update comes out sooner rather then later. Does anyone have an experience as to whether or not this happens cross platfrom on other versions of flash?
