Here is the idea: who needs MDI, ever? Why torturing yourself and scaring out your users?

Do yourself a great favor: do not use MDI at all. You can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don't. I can explain what to do instead.

Solution 1

It seems you are running some code inside the Load event of the forms, which are all run in the main UI thread and thus blocking your calls.

Run the code inside each of the form in a separate Thread or a BackgroundWorker.
