Questionable constraint in
ProportionalSplitterMorph<BR><BR></FONT></DIV>Squeak3.10.gamma.7159,
WinXP/SP2<BR><BR>I have a window with four panes: <BR> top
left: LayoutFrame fractions: (0@0 corner: <A class=moz-txt-link-abbreviated
href="mailto:0.2@0.5">0.2@0.5</A>)).<BR> top right pane:
LayoutFrame fractions: (0.2@0 corner: <A class=moz-txt-link-abbreviated
href="mailto:1@0.5">1@0.5</A>).<BR> bottom left pane:
LayoutFrame fractions: (<A class=moz-txt-link-abbreviated
href="mailto:0@0.5">0@0.5</A> corner: 0.19@1).<BR> bottom
right pane: LayoutFrame fractions: (<A class=moz-txt-link-abbreviated
href="mailto:0.19@0.5">0.19@0.5</A> corner: 1@1).<BR><BR>self addPaneSplitters
does its impressive magic; <BR> a horizontal pane splitter
right across the window at y=0.5<BR> two vertical pane
splitters one between top left and top right and another between bottom left
and bottom right.<BR>(The latter two has
'splitsTopAndBottom'=false)<BR><BR>The curious thing is that the two vertical
pane splitters are linked; any one of them cannot be moved past the other one.
The constraint is in these methods

this curious behavior? The easiest workaround would be to hack
<B>siblingSplitters </B>to return an empty collection. Perhaps it would be
better with a new preference? (Subclassing

practicable).<BR><BR>I'll be grateful for enlightenment about this curious
