I recently started using the Flex 3.3 sdk in Flex Builder. I simply unzipped the files to a folder in the sdk folder and added it via the Flex preferences window and made it the default sdk. However, now when I create a new pure Actionscript project all the code hints for items in the "flash" package are missing. Also, when I open old projects with the 3.3 sdk it removes all the import statement related to that package. So suddenly "MovieClip" doesn't exist.
I'm sure it is some install step that I missed because when I switch back to the 3.0 sdk everything is fine. Any help is much appreciated. Dave
