Bring up Metalworks demo make sure windos manager is OpenWin
Observations
1) Top right iconifiable option doen't work, even on the left side click on small window-icon in front of Metalworks title, the minimize option does not work.
2) Bring any native window on top, after that Metalworks screen does not come on top.
3) From the file menu choose New option it will bring up email window try to type anything in that, it goes to console/terminal you launched Metalworks demo/or beeps. This is not the case for other platforms and window managers.

For Sol-IA8 under CDE window manager it works fine.
