User Control Running Slower in VB.NET 2003


I have been creating a new project in VB.Net 2002. As part of the
project I designed a new user control that presents a string of
numbers in the format I want to see them. It is in fact a control
made up of lots of little text boxes. Using one of the properties I
could disable each textbox by setting its readonly to true and
changing its background colour.

This worked wonderfully in VB.Net 2002, with the control changing very
quickly. I have now upgraded to 2003 and find that the same control
is painfully slow. You can actually see the textboxes changing colour
whenever the control is enabled and disabled. Even though under 2002
it the change was almost instant under 2003 it takes about 1-2 seconds
to change every textbox (about 100) even though I'm running this on
2.4GHz machine with 512Mb RAM. Why on earth has this suddenly slowed
down in 2003? Is there anything I can do about it?
