Changing click behaviour

As a Squeak beginner (on MacOSX Tiger) one of the things that I find
most confounds me is the way that clicking a selected item deselects
it.

Where this bothers me most is, for example, when I want to define a
method in a category where the category already has focus. When I
click back into the window the new method template is not displayed, I
have to select the category to see it.

But the first click on the category actually deselects it, rather than
giving it selected focus. I then have to click it again to give it
focus and get the new method template.

I find the "clicking a selected item deselects it" metaphor
counter-intuitive and would like to change it so that clicking a
selected item simply makes it selected again.

I took a look through the user interface category in Object and a few
other places but couldn't see where this behaviour might be
controlled.

Can anyone help me?

Regards,

Matt
