Hi, just reporting. I upgraded to 7 and experienced the following bug. First, exporting the library (~2.5 MB, ~5000 entries) froze. I aborted the process several times, restarted, and finally toggled BBT on and off. Then I got the but as shown in the screenshot. After that, however, the export worked again and the message never appeared again. I'd say so far, so good. The startup and export performance of 7 is a factor of 3-5 better on my machine. Kr
