Do you use control+F2 at some time before you get the error? I can
reproduce this problem only by terminating the code.... Envi disapear.
Next calls to "envi" produce this error. Doing .reset is enough to bring
back envi and to remove the problem... maybe there is something to
investigate there... (windows, envi 4.6)
