zipping files for pcanywhere can be counterproductive!

the speedsend feature of pcAW compares source & target file, and only sends the update, so a small fix on a 4MB file takes me about 30 seconds to send with a 28k modem, far less than the time to load & unload winzip , PLUS the zip files don't seem to match as well as the .exes, so it may take minutes to send the new ZIP file !!
