Your code only sets the cursor to an I-beam when it is in the current editText
item.  I prefer to have my cursor be an I-beam whenever it is in any editText
item.  After all, one of the main functions of the I-beam is to show where
the insertion point will go when you click.  This information is important
whether there had been a prior click in that item or not.  As the modality
of the current editText item does not affect the behavior of the mouse, it 
should not affect the shape of the cursor.

All you have to do is determine whether the cursor is within any of the 
editText items in the dialog.  You can easily do this with GetDItem and do 
not require any DialogPeek access.

I'm not going to post any armchair code because I would probably make a
mistake and also becuase the method you use to determine what a given window
contains is a matter of personal preference.
