I am a dosimetrist in a radiation therapy dept.  I say that to let you all know i know nothing about computers but i need your help.  I am using a ms dos based treatment planning system  It runs on windows 98.  Recently the programmer rewrote code to make upgrades.  In doing so the print screen capability in the program ( not with the keyboard button) was disabled inadvertently.  Until such time as he can fix the upgrade i cannot do screen captures.  I did try the shft+prnt scrn and at least the printer responded but output was a checkerboard nothing like what was on the screen.  Could someone explain to me how to save the image to a file that i could save to a floppy and then take that to another computer to paste into paint and print etc.  Thank you for your patience.... Carol
