Benjamin Chalupka updated FLEX-33745:

    Comment: was deleted

(was: Unfortunately it didn't happen on my system. A customer reported this problem and I
created this log by installing a debug version of our software. I could never reproduce it
on my system, but we got several customers that got this problem. They were using Windows.
It occured in Flex 4.9 and I tried 4.10 because I saw that there were several changes to the
accessibility handling. But they didn't fix the issue.
In the end I reactivated "Generate accessible SWF" and it worked again.

or expand the try catch block around it.
