Rhino for Mac - updating materials hangs

Hi there,

after updating Rhino for Mac from SR 7.9 to SR 7.12, i am no longer able to update assigned materials programmatically when the Panels: Materials page is active in Tree mode. It causes that Rhino for Mac 7.12 hangs indefinitely.

If i update materials programmatically with another panel open, eg., Panels: Layers it does not hang. The hang can be reproduced reliably if the Materials panel is shown in Tree mode only. If it is set to Grid mode and a material is changed programmatically, Rhino for Mac does not hang.


Hi Clement -

Please provide some code to reproduce this issue.

Hi @wim, i’ll try to extract the relevant parts from the script which is very long and send example files via PM once done.
