Why not just force Dialog_PickFile to do what you want?
Something like this:
------------------------------------------------------------ --------------
;initial directory (optional)
CurrentPath = 'D:\myfiles'
;open a file
filename = Dialog_Pickfile(Path=CurrentPath , $
Get_Path=CurrentPath , /Read)
;process the file here
;save the file
filename = Dialog_Pickfile(Path=CurrentPath , $
Get_Path=CurrentPath , /Write)
------------------------------------------------------------ ----------------
Now every time you open or save a new file, the directory chosen from
the last I/O will be used. This should be platform independent as
well. At least it has been for me on both Unix and Windows.
