I sych my Palm TX both at home and in the office. However, I do find that the first synch at a new location (at home in the vening after synching that day in the office)is very slow. Therefore, I plan to do the first synch in the new location at a time I can leave it cooking for twenty minutes or so. After that, if I synch again in the same location, it takes no time at all. then, the first synch back at the alternate location will be slow.
BTW - I tried opening a small pdf and had the same problem of the devise resetting. As a matter of fact, I created a one page pdf and moved it to the handheld with a synch. Then opened Adobe Reader, and it did not show up. when I tried a pdf that was listed (I don't know how large it was), the reset occurred. I don't know why the pdf I synched to the Palm did not show. Any thought
