<html><head></head><body>Hi Juan, Many thanks for your response. I have used 'Save As New Version'. I had assumed it worked like 'Save', only incrementing the version number. I will try plain 'Save' and see if it works. Also I would like to know what is considered 'user data'? Again, TIA <div class="gmail_quote">Am 15.

However, to my dismay, these windows aren't persistent. When I save a new version of an image, the editor windows are gone. I would like to know why. To the best of my knowledge (which may not be much), the entire current state of the VM should be saved. </blockquote> You are completely right. They should be saved. In Cuis, there are several ways to save the image, all in the World menu. The first 3 might overwrite the existing image file: - Selecting 'Save' will overwrite the existing image file, the previous state (before startup) will be lost. - If you select 'Save and Quit', the image file will be overwritten, as if selecting 'Save' and the system will exit. - If you select 'Quit', the system will ask if you also want to save. If you answer yes, then the behavior is as selecting 'Save and Quit'. If you answer no, your session will be lost (but still the code you wrote can be recovered). - Doing 'Save as...' will ask for a file name for the image file. This lets you avoid overwriting the existing image file. All the previous save options will preserve the state of the image, including all the objects you created (and haven't been garbage collected), and any windows, including text editors. - 'Save as New Version'. This option is a bit different. If you hover your mouse over it, you'll see a post-it note like help bubble, saying that user data will be lost. Let's see how this is implemented. (Skip this paragraph if not interested.) Open a Workspace. Type 'Save as New Version' (without the quotes). Select the text. Now right click and select 'Method Source with it'. You'll get a list with two methods. One of them is #worldMenuOptions. Select it.You'll see that 2 lines below 'Save as New Version' it says #saveAsNewVersion. This is a symbol, a selector for a method. Double click to select that word, right click, select 'implementors of it'. You'll see that the last line of this method does "Try to clear all user state, including all class vars, preferences, etc" self saveAs: newName andQuit: false clearAllClassState: true The key here is the last parameter. This method is specifically asking for all state to be cleared. This menu option is intended for developing Cuis itself. We use it to save the Cuis image file that is stored in the GitHub repo, that should only include the "default desktop", with the Taskbar, a Transcript, and an About Cuis window. Alexander, Folks, would it be more clear if we rename it to 'Save as New Release' or 'Save as New Cuis Release'? Any other suggestion? <blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">I assume there are hooks to run user code after the image has loaded. </blockquote> Yes, this is true, but unrelated to the problem you experienced. If you want, answer back telling a bit about your needs, as there are several ways to do that, and we'd like to give useful advice. <blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> Many thanks in advance.
