Niall,

I commented out all the <TYPE>CODEVARIABLE</TYPE> and received the same
results. I then also commented out all the <TYPE>CODE</TYPE> and received
the same results. We are using VB.NET and the BaseForm is actually very
small. All it contains is a basic Form and has 1 control on it. The
control that I have on the base Form is a Validator Control. If I leave the
Modifier access as "Friend", I don't get the problem. If I change the
Modifier access to "Public", then the template engine consumes lots of
memory. The form will eventually appear, but usually after 5 minutes and
after it has nearly crashed my computer.

You can duplicate this behavior in any simple application by creating a
BaseForm.vb and adding a Validator Control to the form. Change the Modifier
permissions to Public from Friend. Then create a ChildForm.vb and have it
inherit from BaseForm.vb. When you try to open the ChildForm.vb, this is
where the problem ocurrs.

Any other suggestions?

Thanks,

Chris Langston
