File transfer: usually works. gyachi can ALWAYS send a file. The problem (if it occurs) will be when gyachi is receiving a file (whether from a windows client, or from another instance of gyachi) Sometimes a yahoo relay server will use Y14 protocol instead of the older Y7 protocol (we're using Y7). When this happens, there will be a long pause in receiving a file and then the received will see a message about a short file. (expected xyz bytes but only received abc bytes). At the moment, the fix is to drop down to Y6 protocol. Turn the followinf off: setup -> Options -> Enable Messenger-7 Features Note that with Y7 disabled, chat rooms will not work. Photo Sharing: known not to work. It's on the list for the next release. :) Address book (Contact page) known not to work. This will probably get removed in the future. This is an older yahoo messenger feature that has since been depricated/obsoleted. Any problems/questions should be posted at the sourceforge project forums page. https://sourceforge.net/forum/forum.php?forum_id=533966 Project home page: http://gyachi.sourceforge.net/ Sourceforge page: https://sourceforge.net/projects/gyachi/ See KNOWN_PROBLEMS-gyvoice.txt (in gyvoice directory in the source tree) for a description of the known problems with gyvoice.
