Other Application Intrusion
-
I was working much of the day on a number of Sketchup files, properly saving after every few maneuvers. When I attempted to close one of the files a dialog appeared: "This document's file has been changed by another application since you opened or saved it. The changes made by the other application will be lost if you save. Save anyway?" Two buttons, Save and Don't Save were provided, with Don't Save invitingly highlighted. I pressed it and continued to get the same notice each time I tried to close the file until I finally chose Save. Only then could I close the file.
Can you tell me what is going on here? I wonder what sort of intrusion I have Saved and will it cause warts? -
What I can imagine here (though not completely certain) is that you may have had the same file open in two, different instances of SU and after you had changed something in one instance, you got this warning in the other instance.

Interesting to see that the Mac OS presents the same dilemna as Windows. I don't know how many times I have had similar events.
