well, if you say that there are not problem on windows with the same application we could think it's a wine problem. I have a application that use the same process (update a cursor) I will test on linux with wine and I will tell you something =) . Refox is a Fox/Visual Fox Decompiler, what can you do with it? well, the majority of developers when give you an application don't give the code source with it, so you can't change anything. But if this application was made on fox/visual fox, you can get the code source by yourselft using refox =), as simple as that =) http://www.refox.net/-moredets.html
