MX v.2 Components Patch

I am having rendering problems with UIScrollBar and with Alert when using
Patch 1.1.

With Patch 1.0, these components render correctly.
It appears the bug is introduced in functional changes put into files in
mx/controls in Patch 1.1 because I can use Patch 1.1 with mx/controls files
from Patch 1.0, and it works.

I can't deliver code compiled with 1.1 because of the bugs, but I can
deliver with 1.0.
I hope this helps someone.

The problems are:
1) When there is not enough content to need the scroll bar, the UIScrollBar
shows what looks like "SimpleButton" icons where the up and down arrows
would be, and this should be blank. When there is enough content to
scroll, the UIScrollBar is rendered correctly.

2) When I have multiple Buttons in the Alert component, they are drawn too
wide if the cursor is over them. They draw correctly when the cursor is
over them.
