v1.08 (trial) on Mac OSX 10.8.2
I'm playing around with the spineboy example which loads up as default but am experiencing a couple of issues as follows:
In Animate mode, keyframe markers sometimes disappear when posing bones.
Also, again in Animate mode, sometimes the dopesheet goes blank.
Reopening the project restores the missing markers and dopesheet.
I've downloaded the Windows version so I'll give that a go tomorrow to see if I can replicate this on the Windows version.
