(OG 7.21.2)
Still getting occasions where the memory usage explodes upon start-up. I do have a lot of large imported images (source is PDF but don’t think that matters) and the issue seems to occur as the images are trying to be displayed.
[later] I have finally traced some of the images and deleted them from the file. The last two times I opened the OG/file the issue did not occur…but that has happened before and the next file opening, memory usage takes off.
FWIW, I keeep Activity Monitor running when using OG so I can tell when the issue starts.
