Unresponsive script error

[g0ku704]

Hi! First, thank you for the great painting library. I add four paint in one page and each paint is in another div. Only the first paint's icons come and the menu's width become 0 for some reason that I couldn't understand. Also I get the following error;

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

Thanks
