Thanks for your advises! I think I'll start by backup everything on the PC, and "reformat" the REX (deleting all RAM images).
It seems easy enough to backup whole RAM images as "BY" files from the REXMGR so I'll do this regularly in case anything goes wrong in the REX's flash :o) I'll also have a look at TBACK when I get a chance . I think I already asked this on the list, but is there an easy way to create a new empty RAM image for the REX? The only way I found to create a new image is to clone an existing one, and to delete every files in it. I tried to save an "Empty" RAM image for this purpose, but I'm starting to wonder if that wouldn't be the cause of my problems... Eric
