Not sure if it's actually a driver reset but this shouldn't happen anyway.

Reproducible: Always

Steps to Reproduce:
1.Type or select an URL in the location bar
2.Press Alt+enter
Actual Results:  
Screen goes black for a few seconds.

Expected Results:  
Driver reset should not happen.

Should block if D3D10 is going to be turned on by default.

I think I know what this is.

I'll create a patch tomorrow to fix this. This should block Beta 8, obviously.

I don't even need anything in the location bar to get the black screen.  Pressing Alt-Enter anywhere is all it takes.  I don't think it's a driver reset as those usually show up in the Event Log in Windows.

Bas,  Might be related but I'm having problems playing videos on YouTube and CNN.  They start out OK but eventually my screen turns a solid color.  I hear the video and sometimes the player shows usually with a green screen.  In my event log in Windows I see this:

Display driver amdkmdap stopped responding and has successfully recovered.

Forget my last comment.  Seems my video card got overclocked which seems to have caused the problem. Returning to normal clock settings all is well.

It's not, it's simply a DXGI 'feature' where it will happily decide we want to be fullscreen and goes and does it for us.

We don't want DXGI to handle Alt+Enter for us!

Beta 7 blocker perhaps?

Not at all. D3D10 is not enabled by default on Beta 7.
