Passing parameters to wine apps

I'm trying to set up Word Viewer in Wine. While I can run it and even get it to load the document, from the command line, I can't seem to open it, with the document loaded, from the desktop. I've been trying to figure out how to pass the parameter (file name) to the app, in the Contro Center file associations. No matter what I do, I can only open the app, without the document loaded. Any ideas? tnx jk
