Hi,
I applied a manifest to my Windows application and it looks just great. However, I have a problem in one window with a horizontal scroll bar when I try to *drag* it - I cannot do it!

Heres what happens:

With XP theme:
--------------
I click to drag the scrollbar. I get a single SB_THUMBTRACK message, followed by many SB_THUMBPOSITION messages.
The scrollbar does not move.

Without XP theme:
-----------------
I click to drag the scrollbar, I get many SB_THUMBTRACK messages until I let go of the mouse and I then get a single SB_THUMBPOSITION message.
The scrollbar moves correctly.

Has anybody else noticed this behavior and found a solution or a workaround?
