WINDOWS VERSION NETTALK for Windows requires Novell IPX.com version 3.1 or greater. Please note the changes in the documentation NETTALK.doc. It is one of the only software programs that operates in both DOS and WINDOWS. That is, if you have a DOS user the messages will come up in DOS and the DOS user can send to the WINDOWS user and it will popup in WINDOWS. If you are using a DOS application through WINDOWS to ensure that NETTALK will popup correctly, please use the PIFF editor to select NON-EXCLUSIVE option (box NOT checked). Otherwise, NETTALK will beep but not popup when someone sends you a message. You will, in this case, have to manually, select ALT-TAB to bring up NETTALK. Otherwise, NetTalk for Windows should operate easily and simply. P.S. See the file called NetPlus for pricing information on that new product.
