I have been given a proper copy of Photoshop 7, and I have tried to install it on my new iMac, which is running Mac OS X 10.6.2. Fairly soon in the install it tells me something about not being able to locate System Preferences Classic. It carries on installing, but when the install is over, and I click on the icon, it then won't load up, and gives me an error message. Is there any way round this, or is PS7 just not compatible with recent Mac OS..?? I have looked in the System Preferences window, but there seem to be no clues there. Help, anyone..?
