[M3devel] windows move/scroller

[Jay]

I admit I can't remember between NT386GNU and NT386.
At least one of them Juno works on, at least better than I'm seeing on NT386 today.
Juno gets pretty far on NT386. The splash screen comes up, the loading progress,
most of the initial gui comes up, except the "canvas" is full of scrollbar arrows.
 
I'll have to try with 3.6/4.1..
 
A few seconds with mentor and I got:
 
D:\dev2\cm3.2\m3-ui\ui\src\winvbt>\cm3\bin\mentor.exeCreatePatternBrush failed with  0

Maybe a divide by zero since I don't know how to setup mentor usefully..
Looks different than Juno.
 
Calculator works.
