WIP - Undo after gumball

Serengeti (Rhino WIP)
1

Hi all -

A small issue in the WIP. If I do a gumball move, immediately followed by Ctrl-Z (undo), nothing happens. I have to hit escape, deselect the object, and then do undo. Nothing drastic, but a little annoying.

I could not reproduce that behavior here.

Hi Gijs - It looks to me like it resolved itself after a reboot. It occurred dozens of times yesterdayfor no apparent reason, but this morning it doesn’t do it anymore. Strange. I’ll report back if it starts happening again.

Well, it’s back so clearly it starts happening after the file has been open for a while.

It would be good to know if this also happens without the plugins that don’t ship with Rhino, so that we can rule out that option.

If this happens, could you run CommandHistory and copy paste the results? That might give us some clues where to look.
