Here's a run down of the facts so far.

-The problem has been happening in OE and IC.
-It is intermittent.
-It has happened on multiple workstations with different users using different usernames.
-It happened to me yesterday while I was the only one using the system.
-It has happened when using the smart finder and when typing in a part number after selecting "Find".
-It appears to only happen (in OE and IC) when selecting "Inquiries", "Items With Sales and Costs" and not when just selecting "Items"
-When it happens, the item number is highlighted on the grid, the error message pops up, and after closing the error window, the item inquiry window opens with no data in it.
-Deleting the mentioned files and rebooting had no effect.
-I have been unable to reproduce the error on purpose.
-When it does occur I don't know what causes it to go away. Yesterday, closing and opening IC had no effect. Right now everything seems to be working fine.

???????

We have made edits to the grid, so I will reset that to default and see if it makes a difference.

Thanks,

Lucas
