RH8 - Bug - Scrolling down in material browser = Spinning Wheel of Death

Scrolling down (using slider) in Material Browser brings up Spinning Wheel of Death for about 2 minutes, then rights itself.

FYI, I have 13 very basic color materials in my file.

Thx
Alan

Does this happen only with a specific model or do you get the same if you open another model or make a new model with materials?

Just that file.
Tried opening a few different files. It was a tiny bit laggy on one of them, but otherwise, orked fine. Hmph! :slight_smile:

Thx

Alan

Would you be able to share the file with us so we can have a look what’s causing the lag (and get it fixed)? You can send it directly to me (marika.almgren@mcneel.com), or use this page if it’s a big file Rhino - Upload to Support

Meant to get this to you today, but will put it on list for tmrw. Thx

Gah, sorry, I think it was a mess-around file I didn’t save. Feel free to close this thread, and I’ll open a new one (with the file!) if it happens again. Thanks
Alan
