TW does support IE 10+, but I would highly recommend never using IE unless you are required to do so for some reason. As an employee at Microsoft over the past year, I can honestly say that I have never seen nor even hear of anyone using IE for any purpose. It's slow, buggy (in terms of not supporting web standards correctly), and will not be supported by Microsoft for most web apps starting this year (Microsoft will stop supporting Internet Explorer in 2021 | IT PRO).

That being said, I know some corporate environments in particular are pretty weird about mandating IE. For your specific problem, if you can scroll in the normal page (called the story river), but not the edit window of a Tiddler, it is likely the height of the edit window is being limited for some reason. I think there is a setting to control this, but I can't seem to find it myself. However, I think I've seen what you are describing before outside of IE. You can work around this by using the keyboard to scroll the line up and down.
