Back again. It seems that the beta build doesn't actually solve the problem. I use notepad++ to edit lua and xml files (win7 x64) and then save. I expect that BtSync on my Windows will send the files to my tablet (Android KitKat) BtSync 1.4.65.0 but the newly changed files (some are new/don't exist elsewhere) don't seem to transfer across. On the Win BtSync (1.4.10019) with the Android app open at the same time, I see in the Status column "Out of Sync" and if I mouseover it, it says "No Peers online to receive 68.15KB". However if I look in the Peers column I see: "1 of 1 Peer". If I click on that text, I see the newly changed files that have not sync'd across. On the Android side (Win BtSync still open), I can look within BtSync to see the files showing a progress bar all grey and at the bottom, it shows Upload 7B/s and Download 7B/s. They change up and down a few B but don't complete. At a certain point maybe 20mins (not sure why) one of the files might sync but the others will stay stagnant. There is clearly something wrong to make the user wait this long and I don't really believe the 7B/s to be accurate. The Win BtSync shouldn't say "No Peers online..." if the Peers column shows the correct peer IS online. There are no firewall problems and I'm not happy waiting for an indeterminate amount of time for my files to transfer across. Any help would be greatly appreciated!
