Demo - unable to set high resolution

[Kharthis]

There seems to be a bug in the demo in that if the number of resolutions available exceeds the space in the drop list, the scroll bar on the drop list does not actually scroll, but rather closes the drop list. Thus I can only choose the lower resolutions that appear at the top of the list and I can't scroll to the higher ones that should be there at the bottom.

This is on Windows XP, SP3.

Also I can't find a config file in which to set the resolution manually.
