Cannot choose some tabs on player's profile.

in Game menu, U can see "Local Players" on the right side.
If U choose one of them, U have some options to select like "whisper, trade, add as friend, report".

But when I move my cursor to select some of them, the cursor suddenly disappear at some point.

I can guess the current location of the cursor, but it's not correct way obviously.

Plz fix this error.

Thx.
