Thank you Karsten.

I've been making a lot of blunders getting everything in the correct various directories, my fault.

So for Windows 10, The RMB on the displayed Sweep node now works to display the Sweep.htm, for the standard "DARK" display mode of nodeeditor.

For the "LIGHT" display mode of nodeeditor, only a very small white vertical rectangle, with X in it, is displayed. I have yet to investigate any of the code.

Also, either html box persists on top of the MoI screen, when the nodeeditor is closed. So maybe a small cleanup should be done when closing nodeeditor.
