I found the IPF app vey useful, but it has disappeared from my iPad2 twice now and I've had to download it again. Has anyone else had this problem? i can't see any reason for it. I do have my orginal icon linking to the forum, so I can use that alright, but I prefer the other app. Sometimes when I usemy original link, it comes up offering the new app, but just for the purpose, it didn't come up today.
