A query

Hi,
I have query ...if u know the solution then do write back asap..
I am using a JMenuBar and opening a screen by clicking on one of the menu options...If i click on the same menu option again it opens another instance of the same screen...How can i avoid this..I can probably use a boolean variable --- but do you have a better solution..as i hv 20 screens and i do not want to set too many variables.....
