I have the same problem here. This messenger disconnection really distrubing me.
Yes, this problem too. I guess this issue occurs after they updated the skill options feature. There are some problems related to the skill options feature. The disconnections always occurs when the cursor accidentally pointed to any item that possible for having skill options (armors and weapons), gems and other loots are just fine.
Both of that issues already going on for a long time, many tickets already sent, but nothing changed.
I hope you guys GM Team will consider and fix this issue as soon as possible for better gaming experience in the future.
