This is a bug that's been plaguing me also for several versions but I have never got around to reporting it. I use Canola predominantly for podcasts and find it very good on the whole. The auto-bookmarking has been annoying however. Once a podcast is paused, and then re-paused later on, upon resuming it returns to the first pause-point. I then have to seek to the point where I left off (not good in the car!) Seems to happen for pretty much every podcast I listen to.

Also have observed a problem where if the internet connection is dropped or I go offline the file playing stops and I receive "connection to media stream lost, try again?" as if I was streaming the file from the network.
