George,
I haven't seen the problem that you're describing yet, but I know some parts of this software were meant to take advantage of new IE 7 features so I wouldn't be surprised if there was some issues with older Browsers.
Regarding the edit time limit, this software allows for an edit to be made without it showing as such, that's probably why there is a time limit associated with it. Based on recommendations made I think 12 min. would be a decent compromise. I expect Members will use their best judgement regarding this.
