Hi

4.3Aa

After a inserting a record and closing a form I get an 'Invalid Pointer
Operation', this is the call stack



TIB_NodeList.DestroyList($15B2CB0)

TIB_NodeList.DestroyItems

TIB_NodeList.UpdateDescriptors[0]

TIB_BDataset.SysUpdateDescriptors

TIB_Statement.SysUnprepare

TIB_Dataset.SysUnprepare

TIB_Dataset.Destroy

Carousel (my app)



If I post the record and don't close the form it doesn't happen so it looks
like a destruction thing. The only thing in my forms onclose event is
Query.Close (which doesn't throw the error), it occurs in all the cleanup
stuff.



I cant make any sense of this and haven't a clue where to look - any ideas
welcome

TIA

Regards

Paul
