	I have tried this and I also have LDM_Directx running. It was
working fine with K12ltsp6 and edubuntu feisty. Now with Hardy it is
jerky again. I think the graphic driver is wrong because everything is
slow not just flash. How can I troubleshoot and fix this?

the option for hardware

it and restart your

to 9.0.48, you'll see

to access the dialogue.

performance (it was driving

change settings. If you

e.g. adobe.com

	Will this work for other flash applications? We have an app that
calls the flash player to display the program thought http and even
though it works great on the server, it's performance is terrible on the
thin clients. If you can change the settings in firefox will they work
universally for that user is the question I guess. And is there a way to
make that the default for all users?
