Wordworth7 poblems on OS4.1FE -SOLVED

I have WW7 working well from my OS4.1Updt 6 partition
It is in my work: partition and uses its own screen with same characteristics 1920x1080 RGB16 as the WB (also the same characteristics fin the 2 cases)

When i launch the program (from same icon on my WB in the 2 cases)
under oS4 a new screen is opened & drawn up,Wordworth itself is not opened though and the screen is closed.
The screenfont seems to be different on this Wordworth screen (topaz?)

In my user-startup i added a line
assign FONTS: OS4.1Upd6:fonts add
but the behavior remains the same.

Edit:
i just had to copy over the prefs/envarc:Wordworth drawer to the new partition
