If you create a form and perform any activity on the same thread that 
created the form then you will block until that activity is completed. 
Instead you can create a background thread and post updates to the ui 
from that thread by "invoking".

If you are using Windows Forms then you might find this example of 
invoking onto the gui thread useful:

There is also an example of basic threading here:

All the best,
