When I use file open I now get a new window with the previous file still open in the old window. It seems to be the same OpenScad instance though as I can't work on one file while the other is rendering, or even close it. This isn't my expected behaviour on Windows. I expect file open to replace the current file in the same window. I expect a second window to be a new instance, not tied to the first one. Is this correct behaviour on a Mac or more recent versions of Windows, I haven't used anything past 7. Or is is an OpenScad anomaly?

Can't comment on OpenScad, but Office 2013 (Tested Excel) running on Windows 8 does this: 1) Create New. Add data, don't save. 2) File New, as expected opens a new window. 3) File Open, also opens a new window leaving the original window open and with its data in. Notepad++ does the same and looks more traditional. I think it's just different behaviour from ye olde apps. -- ian bradley ianbradley@operamail.com On Sun, 8 Feb 2015, at 04:27 PM, nop head wrote: > When I use file open I now get a new window with the previous file > still open in the old window.

One one document can render at the same time. We don’t have a way of managing multiple instances. To do that, disable that feature and do what you used to do. -Marius
