Details:

Linux Ubuntu 6.10
GCC 4.1.2
GNUstep r25530 (including Gorm) 

Usually when you click a view inside a window or another view, Gorm display
four square corners (knots) which can be used to resize the view. With latest
GNUstep, I observe these control points are invisible most of time or I need
to click several times on special view areas to obtain the black or gray
knots. 

Below you can find a summary explaining how the issue varies with each kind
of controls and how to reproduce it in each case. 
The exepected behavior in all cases is that the control points should appear
immediately on the first click when you click anywhere on the view. 

- NScrollView & NSTableView
If I double-click anywhere on a table view, then I double-click on the
vertical scroller area of the table view, four black knots are shown.

- NSBox
If I double-click anywhere on a box, then I double-click on the label area of
the title area, four black knots are shown. 

- NSTabView
If I triple-click on the content area of a tab view, four black knots are
shown. Nothing happens if click any number of times on the tab view items
area. 

- NSForm
If I double-click anywhere on a form two times (two double-clicks), four
black knots are shown. 

- NSButton & NSComboBox & NSTextField (including labels without borders like
System, System Bold etc.)
I must double-click it to obtain nine gray knots.

- NSPopUpButton & NSSlider & NSStepper & NSColorWell 
No knots at all.

- Radio and checkbox buttons case
If the radio/checkbox button is made of a single button, then the NSButton
issue appears (mandatory double-click to have selection feedback). But if I
turn the radio/checkbox button into a matrix of radio/checkbox buttons, then
no knots are ever displayed no matter how many times I click. 

- NImageView
No knots at all.

- NSTextView
If I double-click anywhere on a text view, then I make a third click in
vertical scroller area, four black knots are shown. This also works if you
just do a triple-click on the vertical scroller area. As a note, time to time
these steps I describe to display the knots doesn't work. I don't really
understand why and it's very hard to reproduce (only happens approximatively
one time in ten tries). 

Quentin.
