Is it Full screen that causes some issue?

I never really paid attention to this, but noticing it more and more. Ive found, that when I have issues with the Flightsim just freezing up when loading, its in Full screen, it did it again today, while looking in Task manager, yep, “Not Responding” . Usually I play the game of figuring out what addons did it. but when I was in there yesterday I had no issues, but today without any changes to addons, it freezes again. Well, without doing anything else. while the Sim was starting up, I switched to Windows mode. Well I’ll be… it loaded up no issues within 30 seconds. Id love to know, if people having this issue, if this happens to them if they switch to Windows mode. Or doesnt it make a difference?
