You shouldn't need to do this.

Isn't this the reason for your UAC prompt?

I think I understand the problem with the log file in this situation, and have 
a patch (see [1]).

But the lock files should be removed when the X server is cleanly shutdown, so 
there's some bit of information I'm missing here.

I wasn't able to reproduce this problem doing some brief testing on W7 (I 
don't have access to a Vista system right now)

There is a manifest embedded in the XWin application [2], but it doesn't do 
anything to affect UAC at the moment.

Do you have some suggestion as to what you think it should contain?
