Just thought I would post some things I've noticed about Calibre running on Windows 7 Beta. Over all the program runs flawlessly on Windows 7. There was only a minor "first run" loading issue that arose.
The following crash occurred only during the initial run when trying to import a previously created/migrated database; Calibre crashed if and only if you pointed Calibre to a previously created Calibre database. To resolve this issue I allowed Calibre to create a "new" database on its first-run in the default folder. I ran Calibre for the first time with all its virgin settings. After this first-run, I made sure to exit Calibre completely. Then I was able to replace the database with
my preferred database.
The only other quirk I found with Windows 7 Beta and Calibre was a rather inconsequential UI bug. Though, for some that have motor or visual impairment it may be troublesome. Here's a screenshot that should show the issue more clearly:
Thanks again for all the incredible effort in creating Calibre. It has brought sanity to my digital reading world.
