NSBrowser resizing weirdly

[Sebastian Reitenbach]

Hi,

I have an NSBrowser in a NSWindow in Gorm, and set its autosizing, so that it 
should resize properly when the window is resized. However, when I first resize 
the window in the application, then the bottom of the NSBrowser jumps over the 
buttons below it, and produces the GAP on top of the NSBrowser. Later resizes 
are fine, and the NSBrowser expands/shrinks following the window, but staying 
on top of the buttons, and keeping the gap on top.
See attached screenshot, left is the Browser in action in the application, 
right side shows how its setup in Gorm. 
I use latest releases of gnustep libraries.

Is there anything I should have a look at? Maybe I'm missing something.
