FTB Launcher version : Feed the Beast Launcher v1.0.7
Minecraft Version: 1.4.2
Java version: Java 7.0.90 64-bit
Detailed description of the issue / how can the issue be recreated:
When playing it often acts as if the right or left mouse button were being clicked, I thought it was my mouse so I changed it but it keeps happening. This only happens when playing feed the beast.
