Internet Explorer: Overlapped I/O Operation Is in Progress

OK, this is a javascript issue, specifically for IE. I hope someone can help.

There is one woman on our test team that randomly gets the error 'Overlapped I/O Operation Is in Progress' when the showModalDialog() function is called.

We pass (url, null, "status:no;scroll:no") to the showModalDialog function, if that helps at all. :)

She is running Windows 95 with Internet Explorer 5.5 on a Pentium 133 (or 166) with 256MB RAM (no, that's not a typo, an honest to goodness Pentium 1). On Windows 98, Windows 2000, and Windows XP computers running IE 5.5 or 6.0, this error does not occur.

The only article I found involving IE and this bug is this one:
http://support.microsoft.com/default...en-us;Q187770, which doesn't actually help.

Anyone have any ideas? Personally I'm pretty sure she needs a reinstall (If not a new computer!), but no one wants to hear that :-P

Could it be a slow hard drive - Windows can't write to disk fast enough for IE sometimes?
