Greetings, Elegant Grid 3.7 Unbound Grid appears to be reliably producing exceptions under the following circumstances: - scrolling is in progress (mouse button down and moving) - timer expires to rebuild the table contents, which removes all rows and adds all new ones (same thread as the message pump) Stack trace: System.ArgumentOutOfRangeException occurred
Message=Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
ParamName=index
Source=mscorlib

I am not sure if this makes any difference, but the message loop for the windows is NOT running on main application thread. I tried a few workarounds, but none are too effective besides tracking scrollbar mouse events and that’s not as easy as may first appear. Suggestions? -A
