Yesterday I was having trouble with SD reliably crashing and shutting down. This happened whenever I tried to use the "spinner" wigit to change my take-off time on a route. I had flown Redhill to Calais and wanted to reverse the route for the flight back. As i needed a flight plan I needed to enter an accurate flight departure time. I pulled up the "flight details panel, went to Take-off and tried to spin the hour number. SD shut down. I repeated this several times with both the hours and minutes spinner. After a few moments of incredulity (SD is normally SO reliable) I realised I could type in the numbers I needed and that worked ok. I had similar problems when I wanted to delay my resulting flight plan - adjusting the departure time through the "Manage my flight plan" facility caused similar crashes and I ended up having to delete the flight plan and create a new one.
