Same thing happens in 1.4.2. Doesn’t seem to happen with any other project. Pretty sure I haven’t done any updates or installed any new apps. I did find however I can still open versions 1 and 2 of my project so I can easily get back to where I was.
I think it might have something to do with this - On version three I downloaded a svg file and imported it into my project. When I go to move something that’s been imported I always move it using the green center dot. Well I forgot it was imported, selected all the child vertices, and then tried to move it by dragging a vertex.
Every time I do this I get the “It appears you are trying to edit a file which is not open” message. Whenever I get this message I have to click the Cancel button like 80 or 100 times before the message box goes away. I think I have to click it for every vertex in the imported object but I’ve never counted it.
This can take a good three minutes of clicking so I always just pkill Synfig and restart it. I then move the imported object with the green center dot like I should and save the file.
This time I was working in the morning when I tried to drag the imported object by a vertex and got the message. I had to go to work so I killed Synfig and powered down the computer without fixing the project first. Is it possible when I powered down that a temporary file or a memory cache was cleared and something didn’t finish properly? I’ve done this error before but always fixed and saved the project before powering down.
Anyway just thought it might help.
Thanks for the reply! And thanks for creating Synfig, it’s cool man!
