Problem with Microsoft Word 98


Given that I am not a rich man, I intend to use my copy of MS Office 98 for some time to come, unless Microsoft start selling the OS X version for $50... (which, of course, will never happen...).
Anyway, with an Aqua Theme in Classic, Word still looks quite good, and one could almost forget that it is an ageing application.

However, I can't make Word open documents by clicking on them-it simply starts up with a new document, and I have to use the Open... command to bring up what I need.

I read somewhere that this could be fixed by rebuilding the desktop, which I did both from within OS X as well as booted in Mac OS 9.2, but to no avail.

Having to use the open command all the time is extremely annoying.
Does anyone have an idea how to fix this?
