I know your probably joking but just to clarify Im not blaming your tx list filtering for the long load time; I am saying the long load time started at the same time we merged that feature in, but background prayers 'appeared' to be working for the prior 7 days (which is a weak statement).  So you have to be open minded and realize its possible that QT is processing invisible transaction data and internally slowing the boot down, but I havent had a chance to look into that yet.
