I haven't been able to consistently reproduce this error, but we have reports of several users opening the notification email sent to the list of approvers and when they get to the Pending Approvals section of the web site while using Internet Explorer 8 they just see checkboxes with no accompanying information. It does not happen with every user either- some can use IE 8 without an issue. We have tried putting the browser in compatibility mode and taking it out. I've also tried doing a complete reset to default settings on the browser too. It does not seem to help. Please see the linked screenshot for an example:

Examining the page source reveals that the task information is there, but the user cannot see the entire block and interact with the Examine Task, Approve or Delete buttons. Would this be a CSS/style issue?
Having the users try FireFox or Chrome fixes this problem.
