Fabio,

CursorRefresh does not create a copy,
it do a ZAP ("CA: Alias") and fills it

You are right there. However, if you change SelectCmd, like change or add the ORDER or WHERE clause, CursorRefresh() will still 'respect' the existing SelectCmd and not the new one. If something is changed in SelectCmd, one has to do a CursorFill(), therefore a new cursor will have been created. This will blank the grid.
