I’m a long time user of Omnigraffle (10+ years). I’ve recently been running into some issues.
ISSUE 1: Jumping
When I’m working in certain files at certain times (ie not all files and on the files it does it in it doesn’t happen all the time) the screen will jump to the upper lefthand corner of the first canvas. When this is happening, it tends to happen every 60 to 120 seconds.
ISSUE 2: Changes Lost
Sometimes when this jump happens, the last 60 - 120 seconds worth of changes that I’ve made will be undone and I’ll have to do them again.
I am working on files that are stored in iCloud.
No-one else is working in these files or has them open (I’m 95% certain of this).
My guess (based on no evidence whatsoever) is that when my file tries to update with the cloud version, rather than pushing my changes put to the cloud it pulls the cloud version down to my machine and overwrites my changes.
I’m also assuming that the jumping happens when Omnigraffle tries to update the cloud instance… though again, I have no evidence of this… just a hunch.
