SQORAS32 an unsupported operation was attempted

We were getting this error when we tried connecting Kewill Flagship installed on a Windows 2003 R2 box (with 10.2.0.3 Oracle client for windows installed) to an Apps 11i instance. This error comes up whenever you try to access the DSN in Control Panel > ODBC Data Sources. A google search returns the first hit in OTN forums: http://forums.oracle.com/forums/thread.jspa?messageID=2195086
