I just installed the new AIR 2.6 SDK but FB4 complains that every swc file in the libs folder is "incompatible with this SDK" when I switch to design view. The application compiles and runs fine, I just can't see it in design view in FB4.
Is anyone else experiencing this issue? I tried deleting my Flash Builder 4 folder from C:\Users\<username>\ and restarting FB4 in case it was a dodgy profile, but it made no difference.
Any help would be appreciated. Thanks in advance.
