I have several installs of Mint 9 on different machines & have a problem with Adobe Flash on just one of the 32 bit installs. When I try to play to play a video on Youtube I just get a black window (Firefox) or a black screen with a "Missing Plugin" message (Chromium).
I have tried removing & reinstalling, using Flashaid to choose between the stable & beta versions, and copying the libflashplugin.so file in from a version earlier than 11.2. Can't get anything to work. Anyone got anything? I'm really stumped with this one.
