btw I cant connect to fp11.4b sad, using fd4.0.4rtm :S edit: disregard that, I downloaded sar, not sad.

I have the same problem if I try to run an AIR project that uses Native Extensions via ADL: cannot place breakpoints anywhere, neither before nor during execution. If I remove the extension from the AIR properties window, it works.

oh-oh I just updated to 4.2.0 and the debugger does not work anymore please help!

all right, nothing worked out. I think I have to stop coding for today

P.S.: ok finally found the solution...I had to point my java home to the 32 bit...however the previous version of flash develop I had installed was working fine with the 64bit version

P.P.S.:damn! now I remember what I did (I blogged about it as well!) I modified the jvm.config file grrr
