IE9 RTM and Citrix ICA files

I ran various IE9 betas and RCs without issue when it came to opening and launching Citrix ICA files.  Once I installed the RTM version however, they failed to open.  The file would download, and then just sort of hang.  If I went to the site with Firefox, I had no issues.  Today I learned that to resolve this, you simply need to uninstall "Citrix online plug-in - web", and then reinstall the web client when prompted through your Citrix portal.  Much better now...
