I have a number of projects that include SWCs with FlashPro assets. When I move them into FB4.7 the SWCs don't display correctly. I've found this solution which lets me set the compiler to 4.6 instead of the AIR 3.4 SDK:
This solves the problem for older projects, but I noticed today that new AS projects with SWCs that include Flash SimpleButtons also don't compile correctly with the default AIR3.4. Is it possible to add to the build path so that Flash simplebuttons will work with AIR 3.4, or is it safer to stay with the 4.6 compiler when a project includes Flash generated SWCs?
