Maybe a problem on the image and the vm side. Even in headless mode, starting pharo creates a window. Even if it is hidden, it has some size. Quit and Saving an image will write the current width/height into the image file. Starting the vm will create a window and set the size of the window to the last size. The window is always created in normal (not-maximized) mode and the available size is a little bit smaller than for a maximized window. Now, the image checks for a change of the size of the current DisplayScreen instance and the actual screen size. If this is different (as in this case) a new DisplayScreen is initialized which will call a full screen update (ioForceDisplayUpdate). And this method will show a hidden (headless) image. > > >> >> On Fri, Dec 29, 2017 at 6:22 AM, p...@highoctane.be <p...@highoctane.be> >> wrote: >> >>> I am using nssm because the service option is broken. >>> >>> The code seems to still be in the image but disabled (there are quite a >>> few things like that actually). >>> >>> Phil >>> >>> >>> On Fri, Dec 29, 2017 at 11:59 AM, Torsten Bergmann <asta...@gmx.de> >>> wrote: >>> >>>> >>>> Hi, (cross posting vm-dev) >>>> >>>> nssm is nice - but requires additional tools. >>>> >>>> Since the days of Squeak the windows VM had the >>>> >>>> -service "ServiceName" >>>> >>>> option and one was able to run Squeak as a windows service out of the >>>> box. >>>> >>>> See http://wiki.squeak.org/squeak/105 for details. >>>> >>>> This option allows to register/deregister with the windows service >>>> manager and run >>>> a headless image. >>>> >>>> I run a Squeak Wiki (Swiki/Comanche) since years with this and it is >>>> very nice and stable. >>>> >>>> Unfortunately this is broken in recent Pharo VMs and so far Esteban or >>>> others did not >>>> have the time to look into this issue.
