>If you want you can send me the form and tables(if they are local). I would need to see the methods that are loading your grid and combo otherwise I would just be speculating

-Too big data and all. I have not succeeded been in isolating the error to a baser class ... Thanks anyway

>One thing you might try is to SET FILTER TO after the grid is loaded to remove the filter for that datasession when you are not using it.

- The grid is always in use and so is the filter for a particular data set. The offending combobox is not bound to the data.

>The other thing to check is to make absolutely sure you aren't using the same temporary cursor name to load 2 different controls with data.

- There are no temporary cursors in use, only a direct link to a table.

Oh well ... Thanks anyway
