Thanks SO much for your reply.
I thought as much, but for the life of me I can't see where to get it.
I'm using the 3.2.0 SDK for builds.
The instructions online at adobe.com say to download the Flex 3 SDK
and the latest .mxp files will be in /frameworks/flash-integration/
but I can't find that directory either in my official download of the
Flex Builder 3 Professional package OR the Flex SDK open source SDK.
Screenshot below of what I see when looking in "frameworks" - and this
is a download from TODAY! No "flash-integration" folder.
Thanks Alex, but there was no attachment. I think they must be getting stripped out, or if you posted via email, the file does not get attached (that's what happened to my screengrab)
