Im starting to play with my "new" Z50. I bought a 128MB CF card, and it seems to work alright. But theres a little problem: when I open a word file (a file stored on the CF), and start editing the file, after a few minutes of writing, when I try to save I get a "write error" message on the screen. But if I try to save the file some seconds after I loaded it, it works alright..... any ideas?
