I had v.0.2 which functioned; v.0.4 crashes with a beep and a query as to where the prefs file is - the prefs file is sitting next to it in the folder. I tried to email the developer directly and had to screw around with Sourceforge.net (which, from my experience, is one of the least intuitively set up sites on the net) and gave up.
Sorry, I'll check back for a later version. Even minimal documentation (with a contact email address!?) would be appreciated.
