help: misbehaving "print topic" javascript in ForeHelp InterHelp project

[Wrdfinesse -at- aol -dot- com]

Hi all.   I'm ~72 hours out from a product release, and Murphy's smacked me with a vengeance.  I've sent the details to FH's tech support, but haven't heard back from them so thought I'd check with you all ...

I've created a "cross-platform" (yeah, I know) InterHelp .html help system using ForeHelp's ForeHelp Pro (version 5.0.2a).  I had (notice the past tense) successfully used the following JavaScript string to code a print function in the navbar of a 3-pane help system (using FH's custom template builder: navbar on top pane, content topic in right pane, TOC in left pane).

       javascript:window.top.frames['content].focus();print()

Sometime within the last three or four builds (the last six working days) the above script quit working.  (It still works when I run the project locally; but once it's merged with the code base it's gehosened.)

When I click the help button (running debugger), I get the following error:

       Line 0:
       Error: 'window.top.frames.content' is null or not an object

Microsoft's wonderful debugger has this to add:

       An exception of type 'Microsoft JScript runtime error:  
       'window.top.frames.content' is null or not an object' was not handled.

<sarcasm>This is supposed to be an improvement over the lamented GPF?</sarcasm>

I've tried (at my developers' suggestions) replacing 'window.top...' with 'self.top...' and 'this.top...' no joy.  The good news is that I can document a work-around (right-click in the topic pane and select print) in the release notes.  But this one is just frustratin' the bejeebers out of me.

Has anyone encountered this and come up with a solution?  I'd appreciate any insights ...

Thanks in advance!

       Anne
