Hi, Valentin, After going over your specs and looking at the screenshots, this is a relatively clear indication of your computer being on the brink of memory "overdose." The aircraft you are loading in mixed with Gizmo and other plugins running globally are chewing up your relatively lower end system. Sometimes we all have to face the fact that we don't have the high end machine anymore (done that twice this year myself already!) and are faced with "dealing with it" or buying a new system. I assume that if you could be afforded the opportunity to purchase a new system you would, but I'm sure there's some reasons which do not need to be explained here as to why you can't or haven't. Unfortunately there doesn't appear to be much I or others can do to help you at the moment. I certainly wish I could say otherwise, however, I am confident in telling you that the moment you are able to upgrade your system and do so, your issues related to this will simply disappear. All the best, Cameron
