Well I downloaded the 64- bit version of 2.2 and i get an error message on start-up : wsjt-x: ENTRY POINT NOT FOUND. (attached) I close it out, get the same error message the 2nd time, close it out and THEN 2.2 runs. Doesnt happen with 33 bit version; I have a 64 bit PC W7. One other odd item - when 2.2 opens, it seems to put out a brief audio tone which triggers my PTT line on the transmitter (I run VOX). No big deal but a new thing since 2.2. jay ny2ny
