That's normal for all applications under UAC. You can't drag and drop from a program at a low security level (eg. a Windows Explorer with normal privileges) to a program with a higher security level (Xtreme running as admin).

This is a deliberate security measure in Vista, to prevent a variety of attacks where low-trust applications exploit broken message-handling in higher-trust applications to escalate their privileges.
