Minecraft Forums

when i try to run multiplayer, a number of java exceptions appear in the terminal window, and i am unable to enter an ip address either for direct connect or add server (the form appears, but typing in the form field produces no characters).

this is on ubuntu 12.04 lts.

any suggestions of help would be much appreciated.

all works fine on windows 7, but i am tired of my kids rebooting my laptop!
