Yesterday, I had an urgent need to password protect some zip files, so I found ZipIt and registered it.
However, half of the menu commands just don't work most of the time- they are greyed out, but randomly become available without doing anything besides clicking on different parts of the interface. Sometimes menu items are available, but flicking to another menu and back causes the item to be greyed out again, so it can't be used.
I have mailed the author but not heard back. In fact, the software seems to be abandonware as it has not been updated since 2002

.
Is anyone else out there successfully using ZipIt on OS X 10.3.4?
PS. is it possible to password protect zip files from the command line?
