On June 13th, Adobe updated their Flash Player to fix a number of critical security flaws. Then, just three days later, another fix.
The new fix seems relatively trivial. On the 16th, the company said "we've updated Flash Player to address a bug that was impacting some Flash content. If you are having problems interacting with mouse button presses or drag and drop actions, we recommend you update to today's release."
The latest version is now 220.127.116.11, except, of course, with Microsoft's browsers.
