For what it's worth ..."me too". Ripper works erratically .. and when it does it takes from several up to 10mins to load the index and usually a similar delay navigating to an actual program or navigating to one of the submenus .. doco, drama, abc2 etc. IF I manage to get into the ep list for a particular show then the speed is as expected & no delays accessing any or more than one episode. In the meantime it sometimes greys out and says "not responding". Running Win7Pro 64bit .. and running the 64bit version of ripper. It seems more tolerant of the first few items in a submenu, keep scrolling down & it goes to sleep. Napper behaves the same, but less successfully. Loading the images does seem to be a clue here .. during the "sleep phase" it displays "images loading" or something like that in the image box.
Maybe a future update could have the option of disabling the download of the screengrab images for both series & episodes? I don't really need a screengrab to tell me what the show is after all.
