I have recently purchased the ixeg 737, first of all, it's a beautiful aircraft, but I am having an issue which is very annoying. each time I make a change in the FMC that illuminates the EXEC light I get these massive stutters which last several seconds each and they are persistent until I manage to press the exec button. after the button is pressed and the light goes out the stutters are completely gone. I have heard other people also have this issue, and I would like to know if there is a fix
