   How to contact to ATI? I found serious bug with gamma settings
  I found serious bug in all latest ATI drivers (since 5.xx), but ATI web site doesn't contain any email address or web form.I'm sent them request to become registered developer a week ago, but I'm still waiting for an answer.If user sets gamma using Adobe Gamma Loader or MonacoEzColor for his desktop. WHen I run fullscreen 3D application (in *same* display mode - same width, height, refresh rate, BPP) I see two problems:- ATI resets gamma to values adjusted in color settings for 3D fullscreen modes. It's very bad for 2D purposes.- And after closing of 3D application I see that drivers didn't return back original settings of desktop gamma.(This problem occurs in any 3D games I tried, if set same display mode as current mode)No such problem on NVIDIA video cards. NVIDIA uses perfect unified color settings for 2D/3D and automatically applies gamma settings for 3D as well as in 2D.So I consider that NVIDIA provides more good support of color settings.   
This page lists all of the ways to "contact" ATI.  Of course, they want you to go through as many FAQs and searches as possible before you hit anything that a human might actually see.  Until they get back to you with the Developer stuff, you could try going to Customer Care -> Submit A Ticket.   ;  Thanks, I'll try again
