Restoring MDI Application Windows positions

[KK]

Dear All
I have an MDI Application which needs to restore it's previously closed
state on subsequent openings.
While closing the application, I am storing the positions of all the Mdi
child windows to a file.While opening I read the positions from the
file,create Mdi Childs and apply positions.

My problem is when I'm recreating the Mdi child windows they are created
and appear in the Z order initially and later they moved to the applied
positions.This is causing some weird effect.Can anybody help me how I can
restore the Mdi child window positions without such effects?

Thanks in advance..

Regards
Krishna
