Procedure Builder crshing on compile

I'm having problems with procedure builder crashing when a procedure in a PLL is compiled. I know that PB has problems with the size of a procedure but this procedure is editable when it is loaded in the editor. There is nothing in he procedure that should require version 2.x of pl/sql its nrealy all standard oracle ddl and dml statements. Anybody have a clue.

using the following configuration

Oracle Procedure Builder V1.5.6.15.3 - Production PL/SQL V1.2.1.6 - Production
Oracle Toolkit Version 2.3.6.9.0
Oracle Tools Common Area Version 2.0.0.9.0 Oracle Help Version 2.1.5.4.1
Oracle Tools Object Store Version 2.2.2.2.0 Oracle Tools GUI Utilities Version 1.2.0.10.0 CORE Version 3.5.4.0.0 - Production

on Windows NT 4.0 with service pack 3

cheers
