I have seen the explorer feature, that opens files looking
for icons and slows down your directory listing. It could
be something similar, but I dont know. The powerprint
software directory listing is 4 colomns, 1-checkbox for
selection, 2- filename, 3- size, 4 mod date. That is it, no
icons, and no options to change the directory listing view
at all. Thanks, for the response. Any other ideas for me
