No error message, when I try to open the catalog, it opens, but doesn't progress beyond openening the grid view, and panels. The message in the main area says "no file slected." Then it remains without any further operation. I've let it remainthat way for over an hour, but to no avail. Once I attempt to open that ctalog, I cannot open any others because the program returns to the bad catalog without offering my usual options.
Reading some posts elsewhere about "locked" vcatalogs, I tried to copy the lrcat and preview folders to a new folder and try to open. That acted as if I were opening a new catalog, but that wasn't helpful, except for the fact that I was able to free lichr=troom to open my research catalog.
Until I can "fix" the stuck one, I'm afraid to use it. Any suggestions would be extremely helpful
