Hi, I don't know if this was mentioned before, but in the Aug 2000 issue of WDJ, 'From the Editor' column, there is mention of gawp - http://www.silurian.com/gawp/gawp.htm which is described as "a weird little tool for interactively exploring Win32 API functions." Not sure how useful this is, but it could be useful for debugging or verification that Wine responds in the same manner is Windows. I haven't played with the prgram so don't know how useful it really is. regards, Christopher
