[George's Kindle]

I am using calibre for more than a year with my kindle 3. However, the new versions of calibre (0.9.17 normal and 64-bit version) need more than three minutes to start up on my windows 7 - 64 bit system. I tested both, the normal and the 64-bit version. And I never had such problems with earlier 0.8 versions.

Is there a setting, which I need to change to allow a quick start?

Any help is very much appreciated.
