[x3d-public] View3DScene in X3D-edit 4.0 on Linux

Tue Jun 1 16:46:05 PDT 2021

Hi John, yes it certainly sounds like X3D-Edit is the cause of the confusion you are describing.

When I try to change and save the view3dscene preferences, encountered the same problem.

Found and fixed the bug in source code, change checked in.

We are still having trouble with a bug that crept in Sunday night, will report when next release is available.

Thanks for this helpful issue report.

p.s. still happy to get improved default locations of linux or macos for any of these tools.
