I purchased RTFtoPDF from app catalog & it doesn't work on pre3. Went to see if it works on touchpad & catalog wants it paid a second time even though both are on the same account. I have gotten many apps from the HP catalog and never found any to not work at all, some work but not so well ...that's part of the life in open source and I accept that. This is the only time I paid for absolutely nothing at all ...I realize there is something in the hp tos that says refunds are not in the picture. I object to this strenuously and I want my money back. I wonder who agrees?
