Hello Ann,
Sorry for the confusing and thank you for clearing things up :)
I was talking about the delta-versions, but reading you're message this shouldn't be a problem at
all. No idea what the exact problem was when i tried to change the SQZ functions, but i thought it
had to do with fragmented records on multiple pages. May be i should take a new look on it.
Regards,
