What's up with the Server 2008 desktop graphics bugs?

When Desktop Experience is installed, Server 2008 provides similar visuals as Vista. One thing I noticed though, is that the desktop doesn't act the same as in Vista:
  1. The drop shadow on icon text may disappear on hover.
  2. The selection rectangle has dotted outline as in Windows XP* instead of translucent.
  3. The selected icons don't have translucent background.
It turns out that the desktop SysListView32 control is styled differently. So now I have a simple startup program that finds the Progman window, then the SHELLDLL_DefView window, then the SysListView32 window, and adds the missing extended styles LVS_EX_DOUBLEBUFFER, LVS_EX_TRANSPARENTBKGND, and LVS_EX_TRANSPARENTSHADOWTEXT.

A more robust solution would create a message-only window in the background, listen for the TaskbarCreated message, and reapply the styles to the recreated SysListView32.

These would take care of 1 and 2, but not 3. May be a call to SetWindowTheme would work, but I haven't tried.

* Similar techniques can be used on XP to get the translucent selection rectangle, but will clear the wallpaper.
