Improve stability

Currently while testing there are way too many cases where SCTT fails, like disposed handles, etc., causing the application to crash. This issue should track many of the unexpected exceptions.

• System.OverflowException: Arithmetic operation resulted in an overflow.
  UnmanagedCodeMigration.cs:232
• System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Icon'.
  GroupedTaskbarProgram.cs:34
