Sorry, I wrote "HP" but in facts I meant "Intel"! Anyway, no newer drivers.
Time to replace that PC...
@R0J0hound thank you for the suggestions.
No doubts the problem is in the graphic drivers, and I for sure don't blame Scirra.
Yet I tremble thinking to comments like "that lousy game crashes as soon as I launch it", no matter how hard you explain that the problem is NOT the game but the driver
A friendly message like "your PC cannot run this game" would be nicer
This evening I will deactivate WebGL in the capx and see what happens.
