Calibre: Small Windows 7 Beta Quirks

[Abisha]

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.

The arrow bug is a bug in the underlying graphics toolkit calibre uses. I expect it will get fixed eventually, once Windows 7 is released.

As for the crash, do you have a stack trace? you can get one by starting calibre with

calibre-debug -g

from a console.

From the command prompt I'm receiving:

link   hasn't been detected!
link   hasn't been detected!

Perhaps I need to reduplicate the error? I'm assuming yes.

Once my relatives leave later this evening I will reduplicate the crash and get you the proper information.

Yeah you have to duplicate the error. The link not found messages are normal and can be ignored

Okay, here's what I get. This should be what we are looking for.

C:\Program Files\Calibre>calibre-debug -g

If there is anything at all I can do to help with any further Windows 7 debugging please let me know. -Abisha

P.S. I'm a student of linguistics, and I've just recently undertaken the task of learning a programming language to enable myself to author my own computer language tools. After much research I chose Python. If there are some tasks that I could help you with, I would be happy to do so. There's no better way to reinforce what you've learned than to put it into use.

Thanks, that helps.
