I have a problem with it, if i click them the internet page opens as normal, but, when i go back in the game, fullscreen option is disabled and the click of the mouse is immediately above the cursor: so i have to click under what i want to click to make something happen. The problem is solved when i enable again the fullscreen but it's a bit annoying doing this everytime i want to check something.

So i just wanted to know if this is normal and if there is a way to fix it.

Does your Window Width and Height match your computer screen?

The difference from full screen and window is that i see the start bar. And the problem with clicking obviously.

Maybe the option "background click" is a problem, it always causes small glitches for me when it's enabled.

No, i think this isn't the problem. I keep background click ever disabled.

which one is your default browser?

Chrome

Does the cursor turn to black when you put it on the link?

Yes, it does. Sorry for late answer.

It also closes whispers and glitches it so you can't send or receive new whispers. It's a Bug that urgently needs to be fixed in my opinion for user convenience.
