can't open FLA anymore!

[beeblebrox]

My goodness... i've got a biiiig problem!

i cant open the latest fla of my current project anymore.
the error is really strange. i start Flash CS3 Pro and try to open
the fla file and a popup appears:

"project_06.fla is already open in another window."

but it is definately NOT.
and it's no problem to open project_05.fla or any other file.

please anyone help me!

EDIT: Okay. sorry. I don't know why. But I just copied the fla file and opened the copy successfully.

Glad to see that you've figured it out...

I just wanted to point out that sometimes Flash IDE never releases the file when you close the FLA file... So, Flash IDE thinks that the file is still open... You have to close the Flash IDE and relaunch it to fix that problem...
