Hi adrien I did the following: I commented the method startup of DisplayScreen saved the image then in a file I put Display setExtent: DisplayScreen actualScreenSize depth: Display nativeDepth. Display beDisplay. /Applications/Squeak/Squeak\ 4.2.3beta1U.app/Contents/MacOS/Squeak\ VM\ Opt PharoCore-1.2-12195.9.image display.st and it nearly worked :) I could interact with the little part. I do not understand why DisplayScreen actualScreenSize does not return the correct size or why I only get that size when I open a image with a display I get correct size so probably that the vm returns a default value when the screen is not started? John? Now what I did was to use image with exactly the same size and use the size returned by DisplayScreen actualScreenSize in one to open the other and I got the same problem Stef
