I've never seen this one before...
 
Someone here was working in a different part of the system and went into AR-A to look up a customer's address. Upon trying to get into AR-A it said:
 
(Caption) Error Reading Form
Out of system resources. Ignore the error and continue?
NOTE: Ignoring the error may cause components to be deleted
or property values to be lost.
 
I clicked cancel and the screen came up anyway. I didn't trust it so I closed it immediately. Thereafter I foolishly thought that maybe I'd try the screen again. It gave a stack fault and then went nuts and locked up.
 
Not sure what to make of it. The machine this happened on has been a bit wonky recently.

Hey, what can I say, we're talented here.
 
But closing Evo and restarting has seemed to fix the problem.
