After debating it internally for a while, I’ve decided that I am no longer going to be able to support Mail Unread Menu on Mac OS X 10.4 Tiger. Since I’m no longer running it as my primary OS, it’s much tougher for me to debug the application when there are issues with it. Since I’m just developing the application in my spare time and don’t have the time or resources that a normal software development team has, I can’t arrange to continue the support. These same reasons are why Mail Unread Menu remains donationware and I would love to keep it that way. Thanks for understanding.
