Bit of help from the computer techo's please

[Dale]

Guys,
Whenever I try to type (on the forum only) I have no access to bold/italics, font size etc and also the smilies wont work. I have to "preview post" and then when I scroll back down to my typing everything is there and I can also select a smiley ..

It's only my home computer .. my pc at work has no problems, so it's not me alright

(to get "me" bold and the "read" smiley I had to preview first .. )

Any help would be appreciated as it is damn annoying ..
