6.5 Beta crash when other station CQ with 6.4.15

Hi Irad:

Beta 6.5 fixes the digipeater but I noticed if listening and other station call CQ (both crashes). Although I told the other station to update the exe file, he used 6.4.15 which caused his station to crash but also crashed the listening station (6.5) both using Digi.

Thank you again Irad. Hope the explanation above is understood.
