Yes this time seemed not enough.

the problem i have is with objects inside a splitter.
If one side gets too small it pumps out pango warnings.
I used the Splitter_Resize() event to detect this and limit the size
reduction of the left hand panel.
That works fine when using the splitter bar.
But then resizing the whole window has left me a mystery as to where a
resize event is triggered.
I tried to make a small test app to show the problem but I found it worked
:-/ !!

So i will study this mail and investigate and see if i can find the resize
trigger, or like you say handle it in FMain.

Thank you :)
