What are the bugs and their workarounds in Flash Player?

Question

It seems allot of questions for Flash/Flex are related to bugs in the Flash Player. What are some of the bugs and what is the workaround. It would be nice to compile a list of known bugs and common workarounds.

Example: In Flash Player 10 the DoubleClick event does not trigger in Firefox. The workaround is to avoid using the DoubleClick event in code.

The SWFLoader memory leak was instrumental in our choosing another platform for our app. I'd love to learn the workaround/fix.
