Dir Sir,

    When I use createImage(int,int) function in Frame, it returns
'null';
when I use it in a subclass of Canvas, it returns 'null' too.
I use it successfully in Applet.
    But function createImage(int,int) is a method of java.awt.Component,

and Frame and Canvas are all its subclasses.
    So, why does this problem occurs?
    Some guru's help?
