WINPT-USERSで開発者のTimo Schulzが今年の4月29日に

Yes, I'm really thankful for each bug report I got. And I guess this
is a WinXP problem. It seems most of the code work for this OS but
some special parts fail (hotkeys, ...). I try solve the problems but
I don't have access to any XP machine.

と言っているので、そういうことらしいです…。
