if you get an error message concerning these ocx files when loading or saving or when sending to the com port  or error 50003 then you need to register these files with windows
error 50003 means you have the incorrect version of comdlg32.ocx

download
comdlg32.ocx
comctl.ocx
mscomm32.ocx
email me if you need help getting cfm to run properly


i.e. 
to register comdlg32
run        regsvr32.exe comdlg32.ocx     
to register this control on your system (copy the ocx into your windows system folder first)

.ocx files can be downloaded from microsoft's website

win3.1 and win98 support files are also available for older versions of cfm
