Its not a bug. Its a current limitation.. and its not a delay your experiencing... it actually wont load the picture until the list stops scrolling. To speed up performance the contact pictures are not left in cache memory so when you scroll them off the screen they are cleared from memory and have to load again.. we attempted to leave them loaded in memory when in an early beta and it made scrolling the convo list very sluggish and lagged... so that was a sacrifice we made for performance.
In the next update we will see if we can load the pictures better and faster, but in the meantime this is the best we could offer.
Oh ok, was just wondering. I'm going to try it out for a few more days but im 99% sure im going to buy it.
This app is simply awesome.
