Butler 4.1.12 has been released, fixing one crashing issue (which only affected those running 10.7.x) and one cosmetic issue. The crasher wasn’t actually a bug in Butler, but a change in how the system deals with ejecting disks. Basically, if you used Butler’s Volumes menu to eject a disk/disk image, Butler would then crash and burn, but only in OS X 10.7 or newer.
(The cosmetic issue was an abbreviations window that wouldn’t disappear if you used it to run a web search while the browser was the frontmost window.)
You can get the update via in-app updates (the Updates item in the Preferences tab of Butler’s window), or by downloading Butler from our site.
Important: Butler 4.1.12 requires Mac OS X 10.6 or later; if you’re using Mac OS X 10.5 and/or a PowerPC-equipped Mac, you’ll need to stay on Butler 4.1.11. If you find issues with Butler on your PowerPC and/or 10.5 Mac, please send me an email and we’ll see what we can do about the problem.
