Rich,

Without readwrite you're not necessarily creating the real cursor. Read up the link I suggested.

Did you create the cursor with READWRITE in the first place?

In any case, if this would not help, then you need to apply a two steps workaround.

Did you also try

select MyCursor.* from myCursor inner join (select ID from myCursor WHERE ...) myTempCursor on ... readwrite ?

It's better than IN (). Inner JOIN works faster than select IN ().

But this would work in VFP9 only where you can use derived tables.
