Exceptions raised


Since I authorized some exceptions to be raised, each time a page, containing a goview or gooverview, is loaded, 2 exceptions are raised. Apparently, it has no impact on the look of the page or on the components, unless we can't make tests with so much exceptions every time we load the page.
Here are the two errors I have :
And my exceptions preferences :
So, I would like to know if these errors are normal and the impact on the page or the components.
It's possible for me to deactivate the exceptions, but i would prefer to correct the errors.

I don’t know about the NotSupportedException.

The GDI+ ExternalException happens when one tries to write out a Bitmap as a PNG file. Obviously we handle it automatically for you, so you shouldn't worry about it.
