It's been some years since I released version 0.2. Since then I've thrown out the COM bit and now it no longer crashes, even a little bit. Also, it's no longer confined to Windows.
I've been using this (or its predecessor) daily for years. If I have any other users out there I'll be pleased to hear from them as it might improve the chances of there ever being a 0.4.
