Here's a rundown of what happened.

The original code file for the form had the following lines (for the form
itself):

           this.AutoScale = false;
           this.AutoScaleBaseSize = new System.Drawing.Size(6, 15);

When the project was converted to VS2005, these 2 lines were left unchanged
by the converter.

When we compiled the code, a warning was issued about the 'AutoScale'
property, indicating we should now use the 'AutoScaleMode' property instead.

Initially, we tried checking-out the form, and adjusting the property in the
designer.  As soon as you opened the form in the designer (on a box with a
different font setup), the size of the form and its controls would be
adjusted, which is not what we wanted.

Our second stab at this was to go back, and just adjust the 'AutoScale' line
in the code file for the form.  While this allowed the code to compile OK, it
still did not solve the problem we were having when we opened the form in the
designer.

Ultimately, what we did was remove the 'AutoScaleBaseSize' line from the
form's code file, as well as adjust the line for 'AutoScale' (to
'AutoScaleMode').  This was as a result of creating some forms from scratch
within VS2005 to understand the behavior.

This has completely solved the issue we were having in the designer.

It appears the converter could have handled this a little better, but maybe
there is something we are not considering as to why it didn't.  Either way,
it has caused us some frustration, so maybe this post will help someone else
out.
