term vs .desktop Corrected

[Grizzly]

Hi

Corrected sorry

I can run a Wine app from terminal with

wine D:\path_to_app\App.exe -O

if I add 

Exec=wine D:\path_to_app\App.exe -O

to app.desktop it does nothing

I can use

Exec=wine D:\path_to_app\App.exe

i.e. no cmdline parameter, it then works but is of no real use without the "-O"

Any pointers please 

Also Icon=path_to_icon\app.png 

does not work either, I just get the standard Wine icon
