App crashes since relase of AIR 2.6, thoughts?

We have an app that allows our home workers to access our games and chat products in one place. It's not been modified for a long while. Since the recent release of AIR 2.6, a lot of our workers have been experiencing fatal crashes, that only give only the choice to close the program.

Here is an example of a Window Crash report we have been supplied with (None of our Mac users have crashed as far as we are aware)

Any one else expericenced similar issues with the release of AIR 2.6? Apps that have not be changed but now fail if AIR is updated. We have currently been unable to pinpoint a particular action causing the ensuing crash but are continuting to investigate. Any thoughts, clues, suggestions etc answers on a post card.
