Problem with autoresizing

i’m trying to use tabbar in combination with dhtmlxgrid. I set the size of tabbar-div in 100% and use tabbar.enableAutoReSize(true,true) to fit the size of tabbar. When i decrease or increase the size of screen via Bottom-Right corner, it works great. But when i decrease the size and after that maximize the screen via maximize-icon, the size of tabbar remains unchanged.
Have you any idea?

Thanks in advance,


please provide the complete sample where we could reproduce the problem
