IE: FormItem.focus gets called many times

[claudiobosticco]

SmartClient 8.0 and SNAPSHOT-2011-07-05
IE 8

I noticed that in IE8 focus method on a formitem gets called many times, you can see it for example in sample SmartClient_Explorer.html#formLayoutTitles
if you modify an item like "username" adding :
focus:"form.getField('email').hide();isc.logWarn('yup')",
and then focus in it

why? is it a bug? FF5 calls it one time only.

with 8.1 and IE8, it's called two times only, way better :-)
