Hi,
>I've sorted it thanks. I'm using Cryptor 5.0 and yes, it does work with VFP9. The problem was resolved, or bypassed, by making sure that I only create the object and register the file once - I preferred to register it every time it was opened, so I knew the data could only be accessed in specific circs, but I wasn't re-opening the file every time the report went to top of page, so I don't know why it failed when going to top of page after page 1. Now I just have to test on a 2Gb file and unregister in every place that I don't want the file accessed.

Glad you got it sorted. Personally, I wouldn't worry about registering files at app startup and leaving it that way. The files are only accessible within your application and, ipso facto, within the app you control who sees them anyway.

>The Xitech number you give is the one on their web site, but no-one ever answers, there isn't an answer message either. Despite getting Cryptor working, I'll think seriously about switching to Netlib if this product takes off - at least they respond to emails.

We've been using Cryptor since about '96 without problems (or need for tech support) but if I was looking at encryption afresh now I don't know what I'd choose. If you're thinking of switching then my suggestion of just 'registering' all files at startup would certainly make the changeover easier.
