Question about tabs

Hi all,

On a few recent courses, on what seems like on my development PC only, the tabs in a published occasionally don't work. For example, I mouse over the "attachments" tab. It changes color, but doesn't drop down when clicked. Likewise, "Exit" changes color, but doesn't prompt the exit dialog when clicked. This seems to be consistently happening if I trigger a security warning, like a pop-up blocker, and then allow the action. If I close completely out of IE, not just the course, and re-enter without resuming, I can have control of the tabs back. If I only close the course or if I resume, then the issue with tabs seems to remain.

This doesn't seem to be happening for my colleagues and support has been unable to duplicate the error, so I thought I'd put it out there to see if anyone had similar experiences. Just trying to isolate the problem a bit in case a user ever runs into this.

I'm using XP 32bit SP3, IE 7.05730, Flash 10.1, and .NET Framework 3.5 SP1. I'm hosting on Articulate Online.

Thanks,

~A
