first I select the table
Then I do a seek
it does'nt work

I traced what's happening in the debugger. After the seek I looked to see where was the pointer in the table. Pointer was at the right place. So in debugger it works ok as long as I check for the the content of the table. Out of the debugger the pointer is not positioned at the right place after the seek.

I replaced the seek by a locate and everything works fine.

Why would I have this behavior with the seek?
