Out of Stack Space with IE9 and ExtJS 4.0

I am using ExtJS 4.0 which works on all browsers except for internet explorer 9. I am getting the error:

SCRIPT28: Out开发者_Go百科 of stack space 
ext-all.js, line 1 character 354281

Has anyone encountered this before? If so, how did you solve it?

I had the same problem but I have to add that I only encountered it with IE9 in compatibility mode.

The error pointed to a line that dealt with a component style. From there I noticed that I had a conflicting config option (the child component had a width that was greater than the parent component).

Yours could probably be caused by a different conflict but that was what was causing my problem.

The first step would be to switch to ext-all-debug.js so that you can get a proper line number, then go from there. Ext 4 should support IE 9, so not sure what the issue would be without more details.
