We have users experiencing the this issue ONLY if they compose email in new windows:
When they attempt to attach email, the attach email windows show blank. When view message button is clicked. A error message shows:
Unable to parse the search query.
msg: Couldn't parse query:
data: [object Object]
However, if there is already an attachment in the email, the attach email windows will not have this problem. This happen in IE 8 and Firefox 14.
