HtmlEditor Problem ExtJs4.2

hi Community,



I have a problem



the following...



I have a window with the htmleditor and some other controls



If I close the window said I have a cursor in oversized size

on my homepage...



I already tried to put the focus at the start of the window on a normal text field but it is useless.



can one give me maybe a hint of you?



the developers of Sencha are particularly addressed...
