putty command integration in 3.7.1

There doesn't seem to be anyway to search the forum, so sorry if this is old news... I just upgraded from 3.3.0 to 3.7.1 and the command/open in putty option failed with "C:\Program: no such file or directory". I poked around the options/preferences and found the command in the "Integration" section and put quotes around it and it's happy now...
