Hi Michael,

V4 FEB 9 is executing on Fedora 27 when removing the 32 bit nvidia libraries, so that part is ok.

However, it's pretty much unusable for me:

1) When drawing i.e. two boxes, then MoI will always select the first box, even when clicking on the second box.
2) I can't select lines or faces within a box
3) When moving from i.e. top view to 3d view, then I first need to click into the 3d view window or otherwise it won't zoom with the mouse wheel (instead, the zoom is done in the top view window).

Please let me know what further tests I can carry out in order to help you track down the issue.

TIA and best regards

Bernhard
