It's a feature, the virtual machines take care to only open the image file as read-only and read it into memory, then close it. Optionally on the macintosh, and always on the iPhone the image could be mmapped by the Virtual memory manager's file vnode mapper instead of being read into memory in a single read. It's only opened as writeable if you save the image. The changes and source file if found are opened and managed like so: /Users/johnmci/Documents/Squeak3.8.0/build/SqueakV39.sources {If found, this is opened read only} /Users/johnmci/Shared/PharoCore-1.0-10451-BETA/PharoCore-1.0-10451- BETA.changes {If found, this is opened first as read/write, but can fall back to read only} The error generated by not finding the changes/sources depends on your image preferences.

Hello all,
I'm getting Ubuntu configured on my new $400 laptop, and just noticed that I can load one Pharo image at least twice w/o any error messages. Is that good or bad? I'm inclined to say it is bad, with caveats below.
I mentioned caveats: I have mixed feelings about Pharo's emulated/ MDI GUI. There have been (rare) times when it would have been nice to be able to do something similar on Dolphin. If there is a reason to run multiple IDEs on one box, having them clearly separated by a single main window has some advantages.
