So just to recap to try and eliminate any misunderstandings...
* I use rox filer. I set the "Set run action..." to run foxit for windows, which I call with a simple script file:
loadapp wine
wine '/mnt/sda2/PortableApps/FoxitReaderPortable/FoxitReaderPortable.exe' '$1'
* I can get a linux app to open a file eg foxit for linux can open a pdf. I do this by clicking the file in rox.
* I can get a win app such as foxitPortable to open by clicking on a pdf file. Foxit opens with the default screen, but without the file.
So what I am aiming at is for foxit to actually open the pdf file that I clicked on.
Thanks for all the help you are giving me!
