I recently downloaded "ShowDT" a file to view varous files (GIF, JPEG, etc.) When I try to load the file my system tells me, "Unable to open graphic library version 39." First off, why can it apparently not open it, and, second, where can I find a replacement file in the event it is defective. What would that file be called? —Speeding along at 14400 via AutoPilot Lou Yurcsak
