Update : Just found out that my code contained 1 undefined object : (new button% [parent panel] [label "Cancel"])
because of which command prompt was opening up. So I defined it as below & the problem is solved now. :) (define btn (new button% [parent panel] [label "Cancel"])) But if some error occurs in run-time, the command prompt still shows up. Is there a way to 'silently' deal with run-time errors? Thanks. ____________________ Racket Users list: http://lists.racket-lang.org/users
