I still have users getting random errors on Quick Order Entry. Everyone that I have talked to said they were just tooling along, entering items and amounts, when it throws a critical.

"Deleted row information cannot be accessed through the row"

Here was a post from another thread about the same issue:

"Regarding the error, a Google search found this comment:

I can't get it to do it, but I'm on the same subnet as the server. I can't do it from home, because I'm on a fast DSL connection. I really think that this may be the issue though... it's very random, but it usually happens with "larger" orders, and with people who are physically/logically "far away".

Is there the equivelant of "Buffer = True" or something that can be done, so that the user can't do any more input until viewstate is completely loaded?
