after updating FP in chrome and firefox to their latest versions i noticed that some elements do not work properly on sites that used to work fine in previous versions of flash player.
I noticed that either some JPGS fail to load or that some actionscript does not initiate to show them. The strange thing is that this still works well on the older FP versions.
I have tested this on 3 different systems and the problem is the same. I have not updated my FP for IE. There, the older FP still works well.
We probably fixed that bug in yesterday's release. Please try 11.5.502.135 if it solve the issue.
