Expanding tree under apache on Linux that doesn't

[UNIX Support_6]

We have been using HP SIR, which uses an expanding tree to allow navigation of information. This works fine with apache (I think 1.3.4) on HP-UX, but with apache 1.3.27 on RedHat Linux (AS 2.1) the expanding tree won't expand.
Can anyone help? Any clues gratefully accepted. Thanks, dave

Unfortunately, nothing gets added to the error log when the page is accessed or the tree icons clicked.

For Information, I have found a workaround for this problem, and that is to open the Page in a separate window (ie. something like: $Date).
Thanks to balaji for his/her reply, I'm happy with the workaround.
