I just tested with a fresh build from CVS, and confirmed that the problem I reported is fixed.

We think its been solved in current CVS. Since the bug has been raised in different forms by many people, we are waiting for some confirmation from a few early testers before we do a new release. Arshi however says that his file was generated correctly with 1.10. That would make it a different beast, since this particluar bug has been around since after 1.5.1 Regards - Avik -------Original Message------- > From: Patrick Nolan <[EMAIL PROTECTED]> > Subject: Re: HSSF Workbook not opening in MS Excel > Sent: 07 Oct 2003 20:04:28 > > Guys, > > Robert Lowe and I were having the same problem.
