if you are max lvl or at least strong enought to farm gold i go in ice crown and only take crafting / common and i let stack build for some hours
they sell pretty high
hum to imidiatly sell or discard you must hold Ctrl. maybe its a bug on your computer that think Ctrl is holded down or maybe your button is really stuck clicked. i have no other clues
should be updated! mist of pandaria. more more zone and more quest per zone beacause at lvl 25 i have did all lvl 21-30 quest and its getting worse at higher lvl. each race should give a bonus like orc more strenght, tauren more health, night elf lower time on ghost, dwarf more likely to loot object.
