I just tried to download the file myself (Dev version) and found that I still get the broken build. I will contact the web guys immediately to sort this out. Sorry for the misleading answer I gave you a couple of hours ago.
Edit: We have uploaded a new build of the RadEditor for MOSS, labeled 5.22
. I have tested it and verified that the disposed object exception no longer occurs. On behalf of the web team, I would like to apologize to you.
