Description of Problem:

Vaio SR1K. GUI install of milan beta3. Reached X configuration at the end.
Got boxes for color depth and screen resolution. Each had suggested (and
they were correct) settings.

I clicked on the little triangle for the alternatives and in each I got
a list of three options. When I clicked to make it go away again, it did
not return to the original suggested settings. It inserted whatever had
the focus even if I had not moused over them and had merely clicked the
triangle to view the options. The one with the focus was unfortunately
not what I wanted for either.

Install to the point of X configuration.
On the page with the color depth and screen resolution forms with the
upside-down triangles to the right of each: 

Observe selected values. 
Click the triangle.
Focus moves.
Click to make it go away.
Selected value is different now.

The suggested values were 16 bit and 1024x768, so those are good ones
to expect.
