Jaytrax uses the Infozip zip dll's. This is the original distribution. Jaytrax - final release 2.2 Jayterax is a finished product. It is NOT actively worked on anymore. Therefore this product is free! The PocketPC version however is worked on and can be downlaoded at: http://www.klaar.com Have fun! p.s. Note that all the Jaytrax songs can be zipped for minimal filesize. Changes from 2.2 to 2.1 - It's FREE! Changes from 2.1 to 2.0 - Added System menus for most common functions (thanks to Mitch from www.sonicspot.com) - Slight re-arrangements of the interface. - Removed register bug.
