Hi Eliot, sorry for my ignorance -- I'm trying to understand if we are
headed for a compatibility glitch between older images and newer VM's, or between older VM's and newer images. The old 5.0-201807260206 VM works fine even without any image changes. Is it possible to do the fix it solely in the VM?

Only compatibility between older images and newer VMs matter. One should not expect to be able to run a new image on an older VM (since a new image may depend on a new feature absent in older VMs). One should expect to be able to run any (compatible) older image on a newer VM. I think there should be no compatibility glitch because by default the new VM maps mouse wheel events to ctrl+shift+option+meta+arrow key, which correctly scrolls and avoids confusion with ctrl-arrow. > > The old 5.0-201807260206 VM works fine even without any image changes. > Is it possible to do the fix it solely in the VM? But the old vm doesn’t respond to horizontal wheel events right?

Exist a way of open a old Stack or Cog .image with CogSpur64 ?
This is a must as with Mohave the only working VM is CogSpur64 .

No. The routes are to - migrate your application to Spur 32-bit and then automatically convert the image to Spur 64-bit - migrate your application to Spur 64-bit Since there is little difficulty migrating most code from V3 to Spur this should be straight-forward. Only a few things are not supported: - Spur refuses to support stable object enumeration via nextObject; one must use allObjects (& the image segment loading primitive effectively answers an array of the loaded objects), so no support for determining an object’s age - floats are no longer represented by Float, which is now an abstract class, so one must test via isFloat, not foo class == Float - Characters are immediate These are pretty minor incompatibilities and provide substantial performance benefits (Spur has a much more efficient GC, and supports a larger heap in 32-bits; Float arithmetic in 64-bits is usually faster and takes less space; WideString access is much faster) What are your concerns? Are you worried that the code will not port? Is building an image from packages difficult? etc... > Edgar > @morplenauta > > > >> On 11/11/2018, 05:20, "Eliot Miranda" <[hidden email]> wrote: >> >> One should expect to be able to run any (compatible) older image on a newer >> VM.
