I am using Codebook 3.0.2 (326) on a Mac. When I access Codebook, all items in the category initially opened are available. I have one category that, if I move to after Codebook is open, it locks up and I cannot do anything in Codebook until I restart it.
I have attempted to re-install the database from Google Drive. It is working without a problem on my iPhone (using the same database) as well as deleting all the preferences I could find (though these were all under STRIP in the library) and deleting the software and reinstalling it. None of these overcome the problem. I do not know why this one category appears to be causing a problem, unless it is corruption in the database that is only affecting the Mac version.
Any ideas how to fix it? Is is a problem with this version of the software (there are no updates available in the App Store, which is how I installed it (and re-installed it)?
