I did some simple navigation tests with V4MD_Client and found that the 
problem lies in the GoToRecord command.

This is what I did:

1. I make a query

2. I cycle forward (results appear ten at a time) - OK

3. To go backwards and display the previous ten results I do the 
following:

v = getposition(gmycursor) - 21
gotorecord gmycursor, v

repeat with i = 1 to 10
nextrecord(gmycursor)

populatefields

end repeat


I discovered that although I go to an earlier record (v),  the 
NextRecord command completely ignores the GoToRecord command.

For example cursor is at position 51.

I send it to position 30, but on nextrecord (gmycursor) the position 
will be 52 instead of 31!!!

This problem does not exist with V4MD (and I am using kRandom).
