select - copy - paste

[buddycl1948]

win 7, secure crt Version 6.7.5 (build 411)
using secure crt to ssh from win 7 to various
sun servers running solaris 10.

the problem i am having:

left mouse to highlite desired copy area, ie ascii text works
as expected; however right mouse copies and then inserts selected
text into the command line. right mouse never pops up picker
menu for copy, cut, paste etc.
