Initiating SpellChecking

Is there a way to have the app spellcheck the contents of a textfield or textarea without the user typing in the field? If the application loads a text file into a textarea, no spell checking happens. I would like to have the ability to tell the system to check the spelling after the text has been loaded.

what spellchecker are you using???

It appears to only start the spell checker after a space as well

Mac? Win? Linux?

I have only noticed it with windows

That’s not really what I mean. I want to be able to initiate the spellchecking actions and show the spelling errors without the user having to type into the field to trigger it, something like a DoSpellCheck() event handler for any control that supports the built-in spellcheck capability.
