I immediately coughed up my $25 for the upgrade of this $40 program, even though I paid the $40 only about 3 months ago. Unfortunately the program has cost me a lot more than that, consuming about 2 hours of my time at this point trying to salvage my Palm information. It hangs every time when it gets to the "Synchronizing Mark/Space Events" after asking obtuse questions prior to the sync that require an "allow" or "don't allow" response with no explanation of what you are actually allowing because they've changed a lot of the terminology evidently. I've had to force quit the program at least 3 times and soft reset the Palm (Zire 72s) at least twice. The calendar on my Palm was blank at this point. Of over 300 contacts, only about 20 or so of them were on the Palm. I'm sitting here wondering if it has anything to do with the fact that I'm running OSX 10.4.3, having upgraded the OS yesterday. Oddly, the prior version of Missing Sync was working perfectly. I had this feeling when I was buying the upgrade that I might be breaking something that was working. I wish I could revert to the older MS and get a refund. As with all things Palm-related, use this at your own risk.
