Thread: Save issue
View Single Post
I had 4 Kernel Panic in my Mac in the last days. All the 4 Kernel Panic occurred when I hit the keys Command + S in OmniGraffle. I had no Kernel Panic in other applications. The only thing in common in the four Kernel Panics is that all occurred when I hit the Save key sequence.

This problem is no deterministic as I can Save without problem. I'm currently doing processes diagram flow in the past four days so I saved several OmniGraffle documents hundreds of times.

Setup:
MacBook Pro ( 1 series ) 1.83 GHz 2G Ram.
MacOS X 10.4.10 with all the security updates.
OmniGraffle Pro version 4.2 (v129.12). Educational License.

I've stopped saving and just let OmniGraffle auto-save feature save the documents. But sometimes I just hit Command + S as a reflex behaviour after editing the document.

Any ideas?
