This is a nice little tip I came across. It does state that Quickr 8.5.1 support for Internet Explorer 9 will be coming in the next fix pack which would be FP32. That kind of makes this tip a moot point. For what it's worth, and if you need to get this IE9 functionality right away, here's how you do it:
A caveat is that if you're running the IBM i operating environment, fix packs for Quickr are usually a few weeks behind the other operating systems. Right now, FP30 is the most recent Quickr fix pack available for IBM i. Based on the frequency of Quickr fix packs I'd anticipate FP32 to be available for IBM i by the end of the year while the other operating systems should have it a few weeks earlier.
