So I have this issue with both Vanilla MC and Tekkit. When my LWJGL goes out of date I have to update specific files in order to stop this annoying as fuck error. The error is that when I press Mouse 3 ( My PTT for TS ) it brings up the ESC Menu. I fix that by updating LWJGL, however, this time it has produced two new errors. Error 1: Pressing Mouse 3 now stops any current movement. IE: I'm moving forward by pressing W, I click Mouse 3 and I stop. Error 1: Booting-up the techniclauncher drops my internet connection for like 2 minutes. Anyone know some solutions? Thanks.
