A simple VB2012 app, being developed on a win7 x64 box, that is creating a datatable and populating a treeview from the data.

The GUI does not error if there is a reference to an incorrect datarow, it just hangs.
I am getting other odd problems when running in the GUI, menus do not perform correctly, mouse clicks are ignored, other small problems.
Yes, it is a clean machine, no it doesn't have any other problems. The OS is not at fault.

Is this part of the x64 SEH mess? Does anyone have a fix for the issue?
