@MCBastos - Hold the press - Breaking News: I can recreate your problem:
I never use Grid view, so I tried it, this is what I got:
Like you I had to kill calibre, after several retries I still couldn't get beyond that. I overcame it by editing gui.json thus:
Code:
"grid view visible": false,
Now I can't get that library to exhibit the problem
@
developers: observe that the data in Book details is not the currently selected Book# 159 at row 1, it is Book #864 at row 87. That is the most recently added book, the one I created yesterday when I was looking at .URL files. The books are sorted on Author (via View Manager). I know it's is not related to using .URL files as format files (why would it be) - firstly I doubt this thread's OP has any, and I have another library where I experience the same behaviour and it has no .URL files.
I installed portable
7.2, and copied over the settings from my regular install - didn't wedge in grid view in any of my libraries. That led my old pal Intuition to say: "Hide the Book details panel in the installed calibre 7.4.". Et voilą, I didn't get the same problem, grid view works fine on all my libraries… if Book details is hidden.
So, I upgraded the portable 7.2 to 7.3, grid view was fine, so I upgraded it to 7.4. Grid view with Book Details (in both positions) wedges at start up… sometimes. It's not consistent, I'd say it was erratic.
Seems to me that a change in version 7.4 is causing this, my guess the Layout related changes.
