I already observed that, when I suggested the experiment - that was why I specified doing the filter and then do a reapplication of the filter using a keystroke before timing the result seems clear to me that the GUI menu and all the mechanism and overhead for getting rid of the preview window was enough that one got differing results each time depending on how it was done I dont think it was the lack of science, consistency and all the rest which caused some unease in the group - more that the fear that the thread could take up more space than it deserves philip =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
