Dont know unless you provide some page code and any css associated with the page.
A large percentage of all problems tend to be associated with the code so when asking questions in the forum it's best either to:
1) Upload the page and provide a link to that page.
2) If you can't do the above paste the code and css in the forum.
Mr. osgood is right of course, but when you say, you are a newbie, I am alloud to ask you to look whether something fundamental is wrong. Ok let's start: what's about your "default settings" (term translated from my german DW)? What I mean is this:
Here you have to put in the path to your browser(s). For my part, I have installed the complete browser-programs (IE and FF) in the main directory of my DW. The advantage is, DW finds the browsers dead reliable.
Man I feel SOOOOOOOO embarrassed now. I tried again tonight and, lo and behold, it works now.
Thanks for your help guys... If it happens again I will let you guys know...
Again I am so sorry to have bothered you
fortune favours fools! Be happy till next time!
