There are actually two issues here:

  1. An exception (null pointer) occurs deep below UpdateColumnWidths somewhere, but only on windows7? testing on WindowsXP and Windows 8 does not reproduce the problem.
  2. Why is no MessageBox shown when this exception occurs and no crash occurs?

It is an access violation that occurs, so I would expect the application to crash.
I think we should first make it report the error correctly in the UI and then solve the problem itself.

null pointer is not an exception but crash. Anything might happen next. The problem was caused by not correctly initializing the LVCOLUMN mask field before the GetColumn() call.
