What do you mean by 'preloading'?
Do you want to create/instantiate whole forms in background,
or do you just need to create some structures and fetch some data?

I am facing the same problem.
What I want to do is, fill the comboboxes with values and fetch some
data. If I do this on form load, or in the constructor, the form
becomes too sluggish...
Is the only alternative to fire a background thread to do the
fetching, and then invoke the forms thread to fill the combos??

And this actually works except for a catch..
Turn the crossthreadingexception off, do the combo filling and then
turn it on again.
Also dont invoke, just fill the combo from the other thread.
I know I am cheating.. ...

Else there is actually no difference if you use invoke, cause it is
finally going to be executed on the same thread...
