Hi,
    While running the sample application controls/control.rbw  I
encountered the following 
error: 
    controls.rbw:1064:in `onAbout'': undefined method `free''
for
#<Wx::BusyCursor:0x2
827db0> (NoMethodError)
        from controls.rbw:1039:in `initialize''
        from controls.rbw:1039:in `call''
        from controls.rbw:1164:in `main_loop''
        from controls.rbw:1164

I''m running wxruby 0.6 on Windows XP.  Is an explicit free call
required
for BusyCursor?

Regards,
Kushagra

The BusyCursor syntax has changed in 0.6.0 ... you no longer need the 
free call. All you need to do is pass a block.
So if you did this earlier:

def onAbout(event)
        bc = BusyCursor.new
        dialog = MessageDialog.new(self, "This is a control sample", 
"About Controls", OK )
        dialog.show_modal()
        bc.free
end

now you will have to do:

def onAbout(event)
        BusyCursor.new {
            dialog = MessageDialog.new(self, "This is a control
sample",
"About Controls", OK )
            dialog.show_modal()
        }
end

This should be :

            BusyCursor.busy {
>            dialog = MessageDialog.new(self, "This is a control 
> sample", "About Controls", OK )
>            dialog.show_modal()

Sorry for the confusion.
