dopus : configure a filetype

[lionstorm]

I want any text format to be viewed through Next3.5 by double click on the file. Problem is the output window is on the WB, not on dopus screen whatever argument I enter (pubscreen={Qs}, output to window, change the icon tool like this screen=dopus.1). Is there a solution besides putting Dopus as default public screen ?

thanks KennyR but that is exactly what I want to avoid because magellan is not running as a WB replacement. Nevertheless I found the trick : use amigaDOS command instead of  WB and add screen=dopus.1 to next {f}.
