Maybe try updating lwjgl. http://www.minecraftwiki.net/wiki/Tutorials/Updating_LWJGL

If that doesn't work, try updating LWJGL. http://www.minecraftwiki.net/wiki/Tutorials/Updating_LWJGL

I believe he is talking about Buildcraft mining wells. So in that case you can't make them mine forward. But, I recommend making a Mining Turtle and fueling it up and then typing "excavate 10" in it. It mines like a quarry.

If you were to do that, the modpack would have to have CoFHCore installed. Then you just wanna find the World.cfg in cofh folder in config. Then you can change the cluster size, cluster numbers, and height limits according to what you want. I have found that putting 20 for the number of clusters and size makes stone the most rare block. So, I would recommend like 10-15 for them. Also, where is says MaxY and MinY the maximum you can do is 128 and minimum is 0.

Actually, I believe its in the World.cfg which is located in the cofh folder in config. So basically it IS a mod. CoFH core, which took over ore generation from Metallurgy in the recent update. To edit them, open the config file and it lists all of the spawning rates for the different ores. If you are trying to lower them then just make the NumClusters= a smaller number along with making the ClusterSize= a smaller number.
