Trader Menu Suddenly Disappear After A Second

[RubberTire]

After making a long journey to the nearest trader, I tried to buy supplies. I approached a trader and searched for an option to view the trader menu. The problem is that the option never showed up. I looked around, aiming at different spots on and around the trader, trying to find the option but it still didn't show up. I moved on to other traders. The second trader showed the option so I clicked the MMB. The trader menu showed up but quickly disappeared after a second. I don't know why these issues happened but I'm sure that my software (Arma 2, Arma 2 OA, DayZ, DayZ Epoch, etc.) were up to date. Also, I'm sure that my MMB is not broken because I could look into a car's gear.

My guess is: it's a server-side issue.

 

The most likely thing is that the server is running custom antihack that is not properly configured.

If your using infistar then you need the update or change the below to false:

 

Close Dialogs ?       */ _CUD =  true;

You're correct I was using infistar. But where could I find this line? Also, when I play in Chernarus servers, the traders act normally.

Update Infistar and this will resolve the problem.
