When I reply to a post when on the MSN Exploreer browser I can do a spell check.
When on Firefox I can not do a spell check even though it has a drop down to spell check this area.
I even down loaded a English Dictionary spell check on 'firefox but can find no icon or other indication it is even there.
?????

Click TOOLS, choose OPTIONS, then click the button for ADVANCED. There you can check that you want spell check done as you type. Works wonderfully! Right click on any red underlined word to choose a correction or add to the dictionary.

Thanks.
I go to options>advanced but see no provision for spell check as I type.
Got the underline but had to go to config and change the layout spellcheck to the 2 option to get it.
I now get the red underline but the choices are very limited such as ccdone gives me the choice of separating the cc and the done!
Separating corrected me quite well.

OK I went back to options>advanced and now see I have spell check as I type checked so guess that is the system.
