PowerPoint 97 PowerPoint 97 jooleigh (MIS) (OP) 29 Nov 99 13:22 After running a slideshow on a laptop, and then running it on a PC, the slides are all distorted with different color lines all through the picture. Should I reinstall PowerPoint? RE: PowerPoint 97 Dreamboat (Instructor) 4 Dec 99 01:20 No, you should probably delete the temporary files on the PC. Close all programs. Go to Find-Files or Folders and type: *.tmp,~*.* in the Named box. Make sure you check the entire C:\, including subfolders. Hit find now. Delete all the files that show up. Then run scandisk and reboot. No scandisk on NT machines, just reboot.
