CheckerBoard 1.63

I posted CheckerBoard 1.63 as a zipfile on my website. Download it now and unzip the contents into your CheckerBoard folder. The zipfile contains CB 1.63 and an updated helpfile. What's new? I fixed a bug in the user book, and added new search features: in the search mask, you can now search with the current board position too, and results of previous searches can be accessed rapidly with new search functions.
