And thank you for pointing me to VirtualBox! I know that my FC12 installation is ancient (and also, using 32bit OS on a 64bit machine is stupid, as I have to use PAE mode), but I have too many "mission critical" things (e.g. my entire typesetting environment for all the books I publish) which depend on it. So, now I can try the latest FC17/64bit and see if all my "mission critical" things still work on it and switch to it if all is fine. Thank you!
Btw, I am now installing FC17/64bit in VirtualBox and will then install the development environment for kindlepdfviewer in it, so I will let you know if it all went smoothly. Then you could just repeat the same on your machine.
