I tried with Flash player version 126.96.36.199 and Its working fine for me in Win7 -Chrome/IE. Could you please try uninstalling the older version and install the latest player.
If the issue still persist, please provide us the exact URL for which you are facing the crash.
Please follow the link Report a Flash Player crash to provide the Flash player crash report.
The cause of the crashes has been localized to the DropShadowFilter and GlowFilter. The crashes stop when we don't use them.
I think if you could share your Flash Player sample application which crashes, it would be helpful to narrow down the issue.
Also mention proper steps to reproduce the crash.
We too are experiencing the same problem. We have about 1000 users that use our graphic editor daily. We have had tens of complaints regarding this problem. At present we are recommending that all of our user switch over to IE. Since IE does not update its flash plug-in automatically, chances are that non of the user's have version 188.8.131.52 installed and therefore they will not be affected by this problem.
Do you have an estimation of when this problem will be solved?
If you're still experiencing this problem, please provide an accessible link to a reproducible example so that we can investigate.
