								G'Day Developers! 
									If you ask a new .NET developer (from the Access or VB6
									world) what is the best thing about .NET Windows Forms, most
									of your answers will be "Form Inheritance" that allows them
									to keep a nice consistent look for all forms. If you ask
									them a couple of months later, they will probably tell you
									the worst thing about .NET Windows Forms is "Form
									Inheritance". This is because they have had too many
									problems with the bugs in the form designer regarding this
									feature. Many abandon them altogether and jump on the user
									control band wagon. Please don't, I have a solution to
									this....
								 
									I think if you can keep the level of form inheritance to a
									minimum, then you may not see the problem or at least you
									will experience the problem less. Anyway even if you do,
									stop whinging and just close down Visual Studio.NET and
									restart. You don't change the base form that often anyway.
								 
									Well how do you keep it to a minimum? Well make the first
									base form without any controls, only code (to make it as
									flexible as possible and avoid having a multitude of base
									forms).
								 
									We try to keep the number of controls on inherited forms,
									and the levels of inheritance to a minimum, because it
									reduces the risk of problems with the Visual Studio Designer
									(you know when the controls start jumping around, or
									disappearing from the Designer, or properties getting reset
									on inherited copies or even the tab order getting
									corrupted). Designer errors can also occur in the task list
									if the InitializeComponent method fails.
								 
									Every form in your application should inherit from a base
									form which has code common to every form.
									See our examples.
								 
									Cheers until next time,
