[imp] Autocomplete blanks page on IE

[Chris St. Pierre]

I updated to Horde 3.3.5 and IMP 4.3.5 yesterday.  Since then, when
composing a message on IE 7 or 8, the autocomplete breaks things.

Basically, when you start entering an address in the To:, Cc: or Bcc:
fields, and there are autocomplete options, the whole page (not the
frameset, but just the page) goes blank, leaving only the toolbar
frame visible.  If there are no autocomplete options, then it all
works fine, so it appears to be an issue with the display of the
autocomplete box.

The issue does not occur on any other browsers that we've tried.

IE doesn't seem to think there are any JavaScript errors on the page.

Any suggestions?  Anyone else seen this?  Thanks!
