CursorFX reverts back to default windows theme in some applications

I have Windows Media Center Edition 2005 which media center is always running (in living room and is my main TV).  When I put the cursor over the MCE Application window the cursor goes to the Windows default theme and loses the applied theme. Move it off the window and the theme comes back. This did not happen with Cursor XP and I have gone back to using CursorXP because of this.  I downloaded CursorFX Last night 3/2/8 from Stardock so I should be using the most current version. I have uninstalled CursorXP before installing CursorFX.  I have uninstalled and reinstalled CursorFX several times - Rebooting after install, but this still happens.  Thought it may be the theme I'm using but the same thing happens with all themes that  come with CursorFX. Uninstalled CursorFX and reinstalled Cursor XP and the themes stays applied. A pitty as CursorFX seems to have better memory/cpu usage.  Is this a known problem, is this by design and is there any fix for this.

Thanks
