browsers/platforms and Javascript and spacing

[chucklasker]

I found a cool service, albeit expensive, that lets you "see" screen shots of different browser and platform results for a URL. I put in a site I've completed that uses a DHTML Drop Down Menu. Two things show up funky on some Mac browsers - the menu is completely gone (I think way down on the screen), and sometimes the category page spacing is funky.

Problem examples:

First page: Row 3, Column 2: Firefox 1.5.0, Macintosh OSX 10.4
First page: Row 5, Column 1: Explorer 5.2 Macintosh OSX 10.3

So, for Firefox 1.5.0 on Macintosh OSX 10.3 and 10.4, and Explorer 5.2 on Macintosh OSX 10.3 and 10.4, there are problems.

Is this something that's unavoidable, or do I need code that looks at the browser and platform and adjusts accordingly? Is there something that can be done, both for the Javascript and the table structures, to fix this? Or, do I need to just forget those users?

If anyone has a Mac, can you tell me if this site looks okay to you?
