Jan, you might want to try checking to make sure that you have Motion Blur turned off in your MSFS settings, which I assume is what is causing that effect on the spinner on your end.
Concerning the canopy, there is also a click spot on the top of the windscreen framing too to open/close the sliding hood. Note that you have to have the side door closed first in order to close the canopy, otherwise the canopy won't move from the open position. If you start out cold & dark (aka, at a parking spot), the canopy and side door should already be open.
Also, for anyone who hasn't tried starting the aircraft from cold & dark, you must know that Ctrl+E will not work. You have to make sure that the fuel system is on, that the mixture/idle cutoff lever is full forward, and then you have to use the wobble pump to build up fuel pressure. Once the red fuel pressure light is off, which is located in the lower right side of the instrument panel (you have to move your head forward to see it (such as Ctrl+1)), then you are able to start the engine with either Ctrl+E or the full start procedure - throttle cracked, 5 strokes of primer, mags on, booster coil/starter.
