Slow MDI forms

[Shawn]

I am working on an app where the main page uses tabs and then within each
tab there are radio buttons on the top to open MDI children forms. The issue
is that these MDI Child forms open kind of slowly. They seem to be spending
a lot of time drawing the controls and they sort of "fade up" when opening.
Anybody have any ideas as to how to improve the performance?

I made all my MDI children separate programs that run in separate threads.
You may also want to try preloading the forms and just hiding them.

Hmm, an interesting idea. And that helped the performance a good bit? You
also had the same problem I guess.
How do you open a form in a new thread? I have done this with Modules, but
don't see a way to do it with a form.

I don't really open the form in a new thread, but any processes inside of
the form are done in a separate thread(database access...etc)
