I am using Sniper client from wiki. Also try Kane client as well. problem i am having is when i am in inventory windows (open inventory chess or crafting table), left click an item that whole stack would automatically jump into chess or out into my inventory automatically. if i have more than 1 stack of that material all of them would jump. it does not happen for default minecraft (i delete .minecraft folder) tia
That happens to me also. I fix it by simply restarting MC. Maybe try to install sniper/kanes jars on a fresh install of MC.
It happens every so often for me. Restarting your client once every few days is a small price to pay.
like some glitch java libs with the keyboard. usually smashing alt shift ctrl keys on both side of the keyboard fixes this lol.
If you use a texture pack above 16x16 (32x32, 64x64, etc.) you need to use the HD texture patcher first. Odds are your texture pack is above 16x16. Unless you have that other glitch, but I only got that once and it was similar to your problem now, but fixed by updating.
So Yeah, I forgot I had a texture patcher installed, then I installed IC/BC and forgot to copy the original .jar back.. Blonde moment!
