I understand this defect has been fixed in the soon to be launched GW7. We have asked that Novell port this fix back to GroupWise 6.5.
Please remember this is a defect in Novell GroupWise, not Formativ, and that we have no control over if/when Novell fix the bug. Given a resolution is very important to you, you may wish to consider reporting this defect to Novell directly. The more reports Novell receives, the more likely they are to do something about it. The defect you need to report is in the token called ItemAttachmentGetCurrentIndex().
