Problems when viewed on a Mac

[macntig]

Have some problems with the website you can see at www.cleartango.com/index_beta.html

These probs are not visible on any PC i've tried, but are visible on my G4 with large monitor

1. The second panel on the right tends to drop to the bottom of the screen under the left side content. Don't want this to happen but after days / weeks of trying to fix problem still haven't found a good answer

2. in the first panel on the right, the content has too much headspace (though the perfect amount on a PC) - would like to decrease this just on the Mac version but again have failed.

3. Have used a blank image to aid with spacing before the words 'Who is it for?' but while this is working fine on the PC version, on the Mac version am getting that image not available symbol, (which I don't need!)

Can anyone help me solve these three probs. Am really up against it time-wise and could do with a hand.

Many Thanks
