I just noticed that 2.7 is coming out at the end of the month! Very exciting as I am experiencing some problems with the current versions. I have one client running 2.6.3 on a 32 bit windows vista machine and a client running 2.6.3 on a 64 bit windows 7 machine. Whenever these two users contact each other via spark it completely freezes the program without going into "Not Responding" status... I have troubleshooted to the extent of running 2.5.8 on both, deleting the user and readding them to openfire. I also tried logging in with my account on his computer and had no problems. The problem seems related to the user. Is there any known way to fix this, or will it be addressed in 2.7?
