I can not currently download Optifine using the automatic installer. It seems to be a bug with Java 8 update 60, considering It just started after I updated my Java. The issue is I can't click Install or Cancel (the buttons "light up*", but clicking on them does nothing). I'm currently running Windows 7 btw. Any help?
NOTE:This happens with all java applications that I use (except for Minecraft).

EDIT: This seems to be an issue with my mouse. It's not fixed, but I can just use tab to auto-select install (or cancel).
