Hi Martina,
There was a bug about mouse wheel with old XFRX so I upgraded my license to last version. When I installed new version, I got an error message "wrong argument type!", reported to Martin Haluza two weeks ago but couldn't get an answer yet. Lines get error below:
IF Type("m.outputname")<>"C"
=Messagebox("wrong argument type!")
RETURN -100
ENDIF
Do you have any opinion?
