Actual problem: I added an item that had no STYLE statement and no defaults in its svg file. An invisible object appears to crash the graphics display part of the glowforge app.
Using Chrome. In an existing Glowforge project. Select an outline, press Ctrl-C, then Ctrl-V.
You can no longer select any objects. The copy of the object does not become visible. If you change the zoom, the window goes Grey.
The only way to continue is to close the Chrome Tab and open a new one, then reenter glowforge and the project. The copied object is there,
All of this worked normally last night. Software update?
