When you run Ubuntu 10.04.1 64 bit with Compiz enabled, you'll notice that You can't control the buttons anymore whitin the flashplayer. To solve this problem, do the following: 1. Start a Terminal window. 2. Type: cd /usr/lib/nspluginwrapper/i386/linux/ 3. Type: sudo mv npviewer.bin npviewer.bin.real 4. Type: sudo pico npviewer.bin 5. Add these two lines of text to the file, i.e. Pico: #!/bin/sh GDK_NATIVE_WINDOWS=true /usr/lib/nspluginwrapper/i386/linux/npviewer.bin.real $* 6. Press "Ctrl+x" to exit and save. 7. Type: sudo chmod 755 npviewer.bin That's it!
