The version of the grid that fixed the bug for us was version 2.5.5228. We downloaded it from:
Package Version 1.1.5228.0 – May 2, 2005.
The bug was caused by issues that occured when switching out of edit mode when the system was under high levels of CPU usage. The reason it worked fine on my dev machine was that the cpu usage was higher in production, so the effect was more severe.
Hope this helps.
