There are some people who make that claim, but I have yet to see 
it proven true in front of my eyes.  So please don't state it as 
if every single Radeon user is going to experience the problem 
you claim as that is not true.

I personally consider it end user misconfiguration until I see an 
actual reproduceable test case which I can reproduce on one of 
the 20+ Radeon cards I have here.

Since the config tool does not handle dualhead configuration, it 
isn't a surprise that users misconfigure it left and right, as it 
isn't a particularly easy process for many to get it correct.

Perhaps users who do have it workign will share their
configurations with those that don't.

I have made this response with the specific intent of not having
all Radeon users scared away by possible misinformation because
one or 2 people have a problem that might very well be lack of
proper configuration.

One thing is for sure though, until an actual bug can be
reproduced by a developer somewhere, then it is nothing more than
an unknown phenomenon which may be a bug or may be
misconfiguration.  Until a bug is proven and a test case exists
nobody can or will fix it.  On the contrary, when a test case 
does exist, which is reproduceable and is proven to not be 
misconfiguration, then someone can investigate what is causing 
it.

I await that test case.
