Sorry, didn't mean to send a short and Curt reply. Javascript:void(0) in the herf will stop the browser from navigating away from the current page. i have used it in similar situations, where an onclick is required.

Hi!

Thanks Nestor, your examples helped at least to point me to the right 
direction although you didn't copy the popup code, but the stuff that is in 
the popup window. But I found the source page and could figure it out, 
although their approach didn't work for me, but see below.

OK, I got the target in the regular hyperlink all set and that works at least 
for those cases where JavaScript isn't an option. I still can't get anything 
from JavaScript. What I did see in the Defintive Guide that one can write the 
JS code into the fref attribute. That causes the browser to render the link, 
which it didn't do before, and it opens the desired window, but it also 
navigates away from the source page and in Firefox at least shows a blank page 
with the text [object window]. It is halfways there, but as bad as before somehow.
But while I was writing this I got another idea that led to another idea and 
some more googling and now I got it. I don't really know why it works, but it 
does work:
<a href="" 
onClick="javascript:window.open('http://localhost:8080/file:/F:/piviviewer/include/help/en_us/Default_CSH.htm#100', 
'HelpWindow', 
'toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,copyhistory=no,resizable=yes,width=350,height=250');">?</a>

What I'm surprised about is that in order to get a link rendered the href 
attribute needs to be present, but when no URL is specified the click on the 
link doesn't do anything, but the onClick event fires and executes the code.

But then I tried a subsequent link / button and as it turns out the popup is 
behind the main window. So I needed to find a way to give it focus and after 
some more googling I got this:

<button onClick="javascript:var 
w=window.open('http://localhost:8080/file:/F:/piviviewer/include/help/en_us/Default_CSH.htm#100', 
'HelpWindow', 
'toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,copyhistory=no,resizable=yes,width=800,height=550'); 
w.focus(); return false;">Help Me</button><noscript><a 
href="http://localhost:8080/file:/F:/piviviewer/include/help/en_us/Default_CSH.htm#100" 
target="HelpWindow">Help Me</a></noscript>

And I got the CSH portion also down and with my little function I can 
customize the button caption or only show a ? or have a text link with custom 
text. I then tried the code without JavaScript enabled to see if the 
<noscript> portion works, but that doesn't do a thing. If anyone knows how to 
add the proper noscript code, let me know.

David
