ietester? site looks very stretched?

anybody ever used ietester to test their websites again multitple versions of ie? well, I downloaded it, but the site looks stretched on all versions of ie, a little less stretched on newer versions. Even stackoverflow.com looks funny (for all versions). I do have ie8 installed, and both of the sites (stackoverflow.com and the other one) look fine on ie8. Anybody faced something similar? I didn't change any settings on ietester.

(Also开发者_开发百科, I need to actually test website functionality, not just see how it looks, so please don't suggest any screenshot things. I would really not like the option of virtualization of OS either)

Those multiple side-by-side IE testing programs are not reliable.

You should use the Microsoft App Compat VHDs (which are free).
