The hotfix was published a few weeks ago. I had been suffering the debug problem on the Mac (193086), so it was time to apply the fix. (NOTE: Unless you are suffering any of the problems listed you are adivsed not to bother applying this fix)
I found the instructions more confusing than they needed to be. They essentially boil down to ‘make a backup copy of your current installation prior to applying the fix’. This is kind of vital, because if you do a straight replacement of the old “Flex SDK 2” folder with the fixed version, and you happen to use charting, you’ll find that the charts.swc is missing!
Also you need to be aware that first time you run the application after the fix, you will need to re-enter your serial numbers.
