After a break of several years, I have got back to PICAXE for a new project. As I am now using a new computer with Windows 7 (instead of XP and a serial port), I have therefore had to use the new Editor (V 6.0.5.9 Beta) and install the USB cable driver (AXE027) in. (Why oh why does this AXE027 installation have to be so difficult?? I still do not know if I have it working.) This new project uses a lot of code from my last program. I therefore copied the last project's code and pasted it into a new Workspace (??). The old project used a 20X2, and the new one will use an 18M2. Under Settings, I can change the type to 18M2. But I cannot save this change. I seem to have been able to make and save a lot of other changes to the old program- required because of the new pin naming arrangement. I have used CNTRL+S to Save, but when I try to close down the Editor, it asks me if I want to save the changes. "No" shuts the Editor down without saving this change. "Yes" asks a question about Workspace Files (??). When reopening a file created by a "Yes" answer, it presents something which is nothing like the file as it originally was. Software stuff. How do I save this simple device change? I have looked through Manual 1 and Manual 2 without finding anything of use, and tried a Search of the Forum. I must be very dumb and more stupid than I thought. Thank you.
