Anytime I try to close the button editor, Rhino crashes. Doesn’t matter if I click cancel or ok or the X in the corner. 9.0.26097.12305, 2026-04-07

Do you get a crash report window @phcreates ? If so can you include your email and send the crash report please and I’ll get that crash fixed.

No crash window, Rhino just closes, even if there is unsaved geometry. I get a little blue wheel for a few seconds and then it just shuts down. Restarting computer didn’t affect it.

Ok I’ll try and reproduce this and get this fixed, sorry for the bother, but thanks for testing and reporting! Ticket : RH-94605 Button Editor always crashes rhino

@phcreates I do not get a crash. Can you run OptionsExport and give me your .rhs file? Anonymous Upload link

That file is very handy. I should have this fixed up for the next release.

If you’d like to get rhino to work for now, it’s worth noting you have two RUIs with identical IDs (GG_Sculpting _Toolbar) and (GG_Sculpting _Tool). If you right click SaveAs for one of these, close the original and open the new Save’dAs one you’ll have no further issues. I’ve tried to prevent RUIs…

Thanks, BUT, when I run Toolbar and then right-click on a selected toolbar and choose Save File As, it actually doesn’t save the one that I selected - it saves a different toolbar. I have just renamed one of the sculpting toolbars in its folder for now & haven’t re-opened it (I don’t need it anytim…

Video…(no matter which toolbar I right-click and Save File As, the Save box always prefills with the wrong toolbar name, and I’m pretty sure it actually does save the named toolbar, not the one I selected.)

Ah yes another bug. Until the next release then I very much appreciate your patience @phcreates !
