Global Spellchecker a free tool that can check the spelling and/or display the meaning of any text that you can select within any application.It uses the MS Word dictionary and thesaurus as its reference. If you have MS Word installed then you already have a world-class language reference installed on your machine.
Global Spellchecker allows you to access that resource globally from any application for both spell checking and meaning/thesaurus reference.
How it works:
Select any text, copy it (using right-mouseclick or CTRL-C), then
launch Global Spellchecker from the ’Quicklaunch’ menu (or a keyboard shortcut).
