Pls Help copying files prob

[falcon eyes]

Hi every one
I have wrote a program to backup a selected folders to another place and it works fine,but there's an issue and it's during the copy process i can't interact with the application
until it's finished from copying for example i can't exit the application or press any button or even moving the application window,so if any one has a solution for this issue i will be appreciate;

post code?
Or try to use background workers for the entire proces.
