See if it happens on the new beta. If it does, I’ll need more details (e.g. if this only happens in this specific project; if renaming your appdata folder fixes it).
Downloaded new beta and deleted all my configuration files, created a new project just to test it and it happens still.
I believe it stops happening after you compile, but it seems fairly random, only thing that is consistant is that after it stops happening on an instance of gmedit it stops forever on that instance.
