Updated my touch to 3.1 yesterday (held off for a bit cause I was afraid it might cause problems :) but got tired of dismissing the update available message.) The crashing problem cropped up today. Checked the forums saw this thread and the notice of the 1.5.3 update. Synced / updated my touch and happy days are here again.

I love Omnifocus. Ditched my Palm and bought my iPod touch just to be able to have a mobile version and am glad I did.

One thing I'm impressed with is how active you guys are with working to improve the program, keeping tabs on the forums, giving advice, and responding quickly to problems.
