Hi,

"Press Spacebar or Enter to activate this control"

Many of you have might have seen this message when running applets

on Windows. One thing I don't understand is even if I press Spacebar

or Enter, nothing happens. The only way to activate the control is to

click inside the border of the applet.

Well, somehow I can activate the control but this message is lying in

my case.

I Suddenly got curious... Anybody have an idea?

Thanks in advance.

Hyung

I think that's a question of where the focus is. Generally, the focus will not be on the applet when the page is loaded, so for the applet to see any keystrokes, it needs to get the focus first (which is done by clicking on it).
