Unresolved still but an update. I saw another post that referenced a similar problem within a GS8 Beta. So I followed that advice, Quit the GS7 app, then restarted it and held the Control key as it loaded. A window with options came up. Decided to be ‘safe’ and not perform any of the tasks. Clicked Continue with all boxes unchecked. Then another window popped up stating the GS Database was corrupt. The app started loading instantly with NO windows at all.
Was able to finally get back to the DeBug area and told it to Auto Repair Corrupt Databases. Still getting blank window. ALSO, if I try to Duplicate a Listing OR change the Listing View, the entire GS7 app crashes.
So, yeah, this is not good.
p.s. Clicking on a listing and then selecting Show Listing in Browser works just fine, so the links to eBay are still there. The listings within the App are just visible and therefore not able to be edited (or duplicated).
p.p.s. As the screenshot shows, the whole top bar is screwy with only two items showing. Been that way since the Time Machine backup restore was done.
