Thanks Mitch. Double clicking the document files might be a cause, but I don談now if it is the cause in my case. I noticed early on with V7 that trying to open the document before the app is launched leads to inconsistent results so I just never do that. Perhaps related to that, I notice there are a few different document file name suffixes that dont seem to e related to any characteristic of the documents themselves. Is there a description of these somewhere?
I知 familiar with the Open With options. I assumed I had that right because usually if you dont the icon previews are not right, but I値l check that out. Would this have to be done at each update?
As for the loss of shortcuts, I guess there is no known workaround for that. I have noticed that with High Sierra and the most recent TC update for it, this is not happening much, and everything feels a bit tighter. From the pattern, I suspect memory issues that seem to be becoming more frequent on older Macs with the newer OS versions.
