I have 7 jpegs 2382x4256 on the film-strip and have used Save All … the computer just hangs - but there is nothing in the Task Manager to say that studio has stopped working?!
You best raise a support request Jack.
If I have several items on the film-strip - and I select one to Save As - the save proceeds OK but! As the Save is proceeding - if I happen to click on any other image on the film-strip - the Save turns into a hang!!! I must use Task Manager to get out. The strange thing is, Task Manager never reports Studio as “Not Working!”
Good find Jack, I’ll try to reproduce it on our side and show it to a dev.
If I click Close All - then click Apply To All - then click Save - it works: all items are Saved. But sad to say, even this closes a lot of files before any get saved!!! Sporadic success.
If I directly click Save All from the File Menu - it hangs.
