Yeah...I'll repost from the other post.
The Internet is moving toward increased use of jQuery. XenForo was one of the early adopters, and now it's competitors are beginning to follow suit--vBulletin 5, Burning Board 4, IPB, and likely MyBB 2.0. Unfortunately, even the most updated versions of IE are simply bad processing jQuery. Developers are as baffled by IE's delayed adoption as I am. So in a way, it is the software at Stratics, but anticipate similar challenges at other major sites as IE continues to lag behind not only its competition, but also technological advancement in generally.
This month, I am hoping to change hosts and complete the upgrade that we had to postpone. This should make the site quicker and more efficient. However, until Microsoft decides to join the rest of the Internet in proper jQuery support, there are going to be IE-related challenges.
P.S. I really want this site to work well, obviously. I'm not very technical and find these types of problems frustrating. My day job (who actually pays me) may give me a pay boost soon, which I hope to use to hire a real life tech admin who can fix all these issues. Sorry it seems like it's taking a long time to fix everything. I'm working on it and hope to get it completed a.s.a.p.!
