I am running Mac 10.4.11 on a MBP 1.83 GHz. My Omnifocus program has crashed more the eight times today on my computer. This does not count my iphone, which has crashed several times today. I have been using this program for about a week. The crashes became much more frequent with the latest update (Aug 11th), but the phone crashes too. The application crashed today on my computer sitting still. I run Microsoft Office 2004. That is about it. Have any other users been getting frequent crashes? Is this program written for OS 10.5 or later only?
