Raytraced views in layouts seems flawed at times

Hello,

in Rhino 6 (Feb 6):

When trying to “move or copy” a layout which contains a raytraced detail view, the little dialog box to choose where to copy to, fails to show up.
Edit: this seems to work once the rendering has converged

Sometimes, when setting a detail view to ray traced, Rhino 6 crashes. This is hard to reproduce.

As mentioned elsewhere, clipping planes don’t work for raytraced modes.

Please fix! Many thanks!

Daniel
