I upgraded to D|S 1.7, found it wasn't compatible with WIN98SE, so I had to downgrade all the way back to 1.4.16 without all the current updates. In the meantime I did find the installation was quite easy, no problems, and it is possible to make the interface look identical to the 'classic' version then save the setup ( I sometimes get 'mouse happy' and screw up the settings!). And you can delete all the other interfaces from their folder, if you look for it.
