i have this problem, when i do my project ..and i model , skin , texture and so on... the tabs on my option bar stacks and increases.. its like the history list gets longer ...this causes serious lag when i try to save or run my animation.

the file size also expands.when i go to edit -> del all by type -> history ...the file size goes back to normal and the lag disappears, but i lose all my skinning and my model looks distorted

pls fill me in on this. what is the correct way to deal with the lag and still be able clear the history list.

thks
