I'm having problems trying to install various bits of software. The Canon scanner software (for my N1240U) and various PD FTP programmes. When I double click on the installers there is a flicker from the icon and a brief flicker on the icon bat and then nothing. I know it's not the drivers because the scanner worked under Panther via PS7 when I upgraded 10.2.8 to 10.3. HOW I WISH I handn't then reformatted the drive and done a clean install!!! It's onbviouxsly the installer intself that won't work under Panther.
