Juha,
I don't know where the first error comes from, but the 2nd one, "jQuery(el).offset is not a function" seems to imply a dependency on the dimensions plugin. Do you have that included? Also, remember that support for jQuery in Ext is brand new and there are bound to be problems. You're doing us a great service by working through the examples and documenting what you find. Thanks! Mike
