help 2: dparsf

hi,

the previous error i brought up was fixed by adding the line
    "rest_Fix_Read_Write_Error"
before initializing dparsf.

however, the time between pressing the bottom "run" and actual data precessing is much longer  in the linux environment than windows (just now i experienced a 15 min lag).
so is the time for data precessing.
what might the problem be? how can i fix it?
i'm currently using double systems on my laptop, which are windows XP and linux fedora ver 12.

many thX
