Removed all scripts from upper pane.
Delete All from server results pane.
Clicked the X button to close it down.

The virtual server it was last connected to had been brought down prior to my actions.

Exception follows:

SQL Multi Script 1.0.0.552

Object reference not set to an instance of an object.
NullReferenceException

Hi,

Thanks for the report. I've checked the code, and the point at which it's blowing up is just a call to BindingList.Clear()... so it looks like it could be a bug in the DevExpress grid.

Is this something you've seen multiple times, or was it just a one-off?

Thanks,
Robert

First time...

But there again, I rarely reboot my machine unless it's essential...
