The latest update is fairly flakey on the iPad 2. Some buttons along the top and bottom only work in certain device orientations. A few (like login!) don't work for me in any orientation. The usual tricks of force quitting, restarting the iPad, or deleting EarlyRetirementForum and its data and reinstalling don't correct this. (This "feels like" an uninitialized data bug, which often leads to behaviors that vary wildly from user to user.)
Prior updates worked very well, and I found EarlyRetirementForum faster to use than the web browser interface.
