Hi, I am a very happy PA60 owner also, I did tun out of space in the user styles area, but I have RE-PLACED the FACTORY styles I do NOT use, and I have not installed yet a hard drive in my PA60, and by the way, the one that has shorter keys, is the Pa 60 not the PA 50, the 50has LONGER keys and of course, are 100% compatible, if you want to re-place some factory styles, first you must disable the protection, I thing is the last page in global or disk?....I don't have my board here, mail me if you need help.
