Here's the thing, when you hover over "Share" or "Email", the ShareThis form pops up. When you close it, you can't click on "Link 1" anymore (or anything that was covered by the ShareThis form for that matter).

Any idea how to work around this issue in IE7?

I tested it in ie9 with ie7 mode and there is all correct.
