I can't buy or sell stuff so i am block

[Kelgar]

Hello, my problem is i start new game today and now one of the main quest is to buy the weapon of our friend to the merchant in the city. The window for buy/sell stuff open and close at the same time (like i press the mouse button two time) and when i manage to let stay the window buy/sell stuff i can't buy or sell nothing. Did anyone know hot to resolve?
Thank you ( English is not my first language so i hope i describe the situation at best)

that's weird. maybe something is wrong with your mouse, like you accidently double click? did you try a different mouse, or a controller?

Hello i discover how to resolve the problem (not me another one on forum of diablo 4 https://us.forums.blizzard.com/en/d4/t/game-breaking-vendor-bugged/160445 ) ,it needs to set the right time zone on your computer ( i mean set to automatic) and after that i can buy/sell stuff and no bug of doble click.........shame to blizzard to not resolve this bug
