Thanks for answering.
For the sake of precision the unsupported glide call thing generates a flow like this in the status box
CONFIG:Loading settings from config file dosbox.conf
MIDI:Opened device:win32

but I understand this may not mean that much.
As for the crashes, I checked it all again and in fact they seem to be only related to the fullscreen arrangement, and alt+entering in and out of it won't resume the game. The windowed gameplay is really good Glidos-like quality 😎
Is full screen really not (yet) implemented with the present cvs glide support ?
Or in the config file, since no output and scaler joggling seem to fix anything, do you think customizing the
fullresolution & windowresolution settings (which I set to "original") may be a workaround ?
