Hi, sorry it's not working - i'm running btsync on my treo, set to sync to my work pc (and i'm certainly not within sniffing distance of that 24/7...).
i have had the hanging problem that you mention, but only very occasionally - typically when it's come on overnight - and my security app has locked the device.
To be honest, don't know hat to suggest, other than mailing the developer to check known tx compatability problems.
