I haven't run across this issue with my old ISP running Framework 2.0 so I'm hoping someone here has and can offer some insight. I've been reading about Browser Definition Files and I'm thinking this problem is related. Here it is; Some of the style elements in my html tags behave differently when I develop on my home machine(XP SP3, VS 2008, IE8) and then upload to the Winhost server. I'll give you one of several examples. I have a table that looks great when developed on my home box. Then when I upload to Winhost, the table sets 200px's farther to the right than it does on my personal pc. This makes maintenance a nightmare. I'm sure it's something simple. I don't have any special Browser Definition Files in a APP_BROWSER folder. Has anyone here run across this yet?
