Hopefully Ruben's upgrade this weekend will be useful in sorting this out. If he experiences issues, then that would point to a php problem. If not, then I think it's some weird combination of users' computers and knowledge of same that's causing the issue. I haven't looked at stats recently, but I'm sure the bulk of our users are using IE, and the complaints are only from a handful of them. That points to a desktop problem rather than a server problem, but we'll see.
