This is driving me nuts and I cannot figure out why Omnigraffle is doing this. I recently upgraded to Lion and I am running Omnigraffle Pro 5.3. For some reason Omnigraffle will suddenly decide to resize, or actually zoom, the document I am working on. I have disabled "Auto adjust the canvas size" in the Canvas: Size pane and I cannot find anything else that might cause this.

For example, I'll be working on a bezier curve and I have the magnification set at 150%, I'll twiddle a point and all of a sudden Omnigraffle starts jerking the image and zooming it in, moving it around, and will eventually settle at some other - apparently - arbitrary - size, the latest was it jerked from 150% up to 225%. I did not ask it to do this and the size is inappropriate - I don't want it, and while it is jerking away I cannot do anything and I do not know when it will stop. Nor do I know what started it!

Any ideas how I can stop this?
