I have one application with more than 30 grids. Every grid that i create, this method calls doc.createElement('style') (Ext.util.CSS, createStyleSheet), and i found in this that IE have a limit tag style into the tag head.

when i create more grids, whose renders faileds and ie throw a javascript exception.

i read this post and say that will fixed in the ext 1.1 Beta 2, and i use ext 1.1.1 RC1 and is not fixed.

Anyone have a solution?
