spellCheckWindow(strfield1 [,strfield2...] )

The spellCheckWindow function opens a spellchecker dialog similar to that of MS Word.

Any number of fields, HTML elements or iFrames can be spell checked at one time.  The strings or properties to be spell checked are added as a comma separated list of object paths in string format 

Examples:

oSpell.spellCheckWindow('textarea1')
oSpell.spellCheckWindow('document.getElementById("textarea1")')
oSpell.spellCheckWindow(''textarea1'',''textarea2'',"textfield1")
oSpell.spellCheckWindow('strMyString')
oSpell.spellCheckWindow(any_property_or_variable)
oSpell.spellCheckWindow('iframe1.document.body.innerHTML')

Before opening the spellchecker window, you can double check for spelling mistakes in all of the the fields at once using the spellCheckWindowTest method.
