Frequently now since 6.0a, Logos fails to start. It bounces for awhile and then just stops. I never see even a small window saying its working. Even if I abort it, it will not come up the next time. The only thing that fixes it is to re-boot my computer. Then it comes up and acts like nothing has happened. This may have something to do with it aborting some component of the operating system, but I see no evidence of it.
Has anyone else seen behavior like this? Before Yosemite and Logos 6, I could go months without rebooting my computer. I have an iMac with plenty of memory and disk.
