Some internal exceptions

GoDiagram 2.5.2, VS 2003

First, bring up the Exception settings dialog from Vs 2003 Debug->Exceptions menu.
Then select "Break in the debugger" for all the types of exceptions.
Then open the sample Demo1 project. You will get an exception when creating new GoPalette object.
I got one in my program when creating a GoOverview object. But this does not happen in Demo1.
The exception message is the same, like:
A first chance exception of type 'System.ArithmeticException' occurred in northwoods.go.dll
Additional information: Overflow or underflow in the arithmetic operation.
Could you look into this please?

Yes, that’s expected. We handle it, so you can ignore it.
