Thanks Mark
I put the following code into a proceedure in the Menu designer & it works great!
LOCAL lcFile
lcFile=JUSTPATH(SYS(16,1))+"\GABHelp.chm"
RUN /n3 hh.exe &lcFile

Got your other thread suggesting "set path to GABHelp.chm" because am running vfp7. That is not a good option because have 2 chm help files in this application and also couldn't open the help file at its max size. It seems also had problems with context sensitive help.

Anyhow, this works. Thanks again.
