I've been having this problem since at least version 7. Running the Library maintenance doesn't do anything. The debug script is
Code:

And that's as far as it gets. If I click on the gui splash and force close, it typically works from then on until I reboot my computer. Sometimes it freezes also when I delete a book or a format. I have installed the latest version and it still does this.
Thanks!
