Don't quite understand here...your image is hard to interpret without context. Don't think I've ever had this problem.
If striping down your project is too much work, maybe you could try a video?
Do you have another install of construct, like a sandbox version, you could try?
Does it happen all the time, or randomly?
Have you tried a new, test project, or is it just your project?
Hope someone who knows more can chime in.
