OK saving my life at the end of the summer is a small redesign job for a site whose admins primarily use windows and whose users are more likely to be viewing from quite old computers (with old OS'). BUT they wanted the site redone using CSS hence i've been very careful using all the IE conditional comments. I tested the site on parallels with a program that allows you to test the site in IE 3.0 ~ IE 7. In all but IE 3 and 4, the site renders perfectly (IE4 won't read some background images). I should also mention in case it's important that I made the pages in PHP (because they will need to use some scripts in the near future). Now, the problem is that whenever I send them a link to view the site, they tell me that the divs on one half of the page, which is actually a different php file, are overlapping. This was the problem I had BEFORE I wrote the stylesheet for IE, but I can't work out why on my computer everything looks fine and on theirs it's coming out wrong. Does anyone know of any settings in IE that might cause this? Would it make a difference if they were using an older OS (I'm using XP in parallels)? I've been trying all morning to replicate the same problem, but I can't.
