"Object doesn't support this property or method" ...aw.js

On some browsers (IE), I get this error:
"Microsoft JScript runtime error: Object doesn't support this property or method" when the page first loads (without the grid being created yet).
the debugger points to line 32 in aw.js:
"AW.System.Control=AW.System.HTML.subclass()...etc"
This happens before the grid object is even created, must be from the script reference at the top pointing to aw.js.
If I continue on, I get an object is null error on the grid, of course, it can't create it at that point.

Works fine on some, not on others, what gives???

I have a few users in the exact same situation. Has anybody found a solution or at least a possible explanation?

Jeremie,

could you change the script reference from /runtime/lib/aw.js to /source/lib/js and check which line produces this error?

Why has there been no fix for this yet? I see others have reported the same or similar problems, it appears to happen when the mouse events are being assigned in aw.js. We want to buy the commercial version but this is preventing that.
