ACK with one question.
User Interface Privilege Isolation is usually used only for specific
windows of
system security applications (anti-viruses etc.), so with this patch
mouse will
be irresponsive for these windows but keep working for the rest. A
complete
solution might be switching to server mouse mode while the agent is
still active.

layman question: Isn't there a more specific UIPI error code?
I'm afraid there isn't one.
"This function fails when it is blocked by UIPI. Note that neither
GetLastError nor the return value will indicate the failure was caused
by UIPI blocking."
