A couple of things.
First, you mentioned using an Image map in a Snippet? Hopefully you aren't going to all that trouble. Hopefully you realize that you are able to make a simple image a link without resorting to an image map.
Secondly, you may want to investigate using OverLib.
Helpful and Handy Links
Thanks for getting back to me so quickly; much appreciated.
The "Close" image and text snippet is included in fifty or so similar topics, each one presenting the text and user responses of pre-recorded messages, which can be generated by the users' application. As I used just the one snippet and included it in each of the topics, I figured I have just the one place to update it, as necessary. I placed my own image as the hook for the link, as there isn't a convenient image in every topic. Is there any processing or other overhead in using a snippet, rather than a simple link, as you describe? I'm not a rookie, but far from a guru - this was one of my bright ideas, to put user docs online. For once, management listened to me, and now I'm the RoboHelp "expert". Glad I followed up though, as this is a nice product for the most part, and it opens up a few more doors for me in the wonderful world of contract tech writing.
I'll definitely look into OverLib, as you suggest. I'm assuming the answer to my question on bypassing RH's reluctance to work with Firefox on positioning prompted this suggestion?
Bit of a shame really. You spend countless hours trying to placate the IE gods on every other web site you put together, and for once, they get something right!
Anyway, thanks again for the help.
