I made a few changes and fixed a few bugs on CasualPConc.  I guess not a lot of people use it, so I won't go into details.  You can download the new version here.

I also updated the documentation on CasualPConc.  Now it covers most of the features.

A new addition is CasualMultiPConc.  This new application is based on CasualPConc and can handle more than 2 parallel corpora (up to 5).  This is my attempt to answer one request to make CasualPConc handle more than 2 corpora.  CasualMultiPConc has very limited features and it may still have many bugs (as much as CasualPConc).  You can get more information here.
