Thanks for the suggestions, madmumbler - I actually realized that about removing the text between the quotes after I posted this. Dumb.

As a matter of fact my client (who is also working on the site in parallel, don't ask) managed to get the wide logo to show - by making the page 980px wide! I have myself raised the issue of people with 800x600 displays but it didn't seem to make an impression, I'll mention it again - I myself don't really have a feel for who uses 800x600 displays but you obviously do. Since I think he created the wide logo (which really does look nice) maybe he can shrink it somehow...
