When I click in the layer manager, I get the following message.
"Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.
Index -1 does not have a value"
Then, under details, it says
"Application does not support just-in-time (JIT) debugging"
The weird thing is that I was just in this drawing for about half of the day with no problem. Please help!
