It looks a good program, but hugely more than I need. QuickView Plus is so simple the only evidence it's there is the name on right click menu.
Compatibility seems to do the same as the menu itself.

When installing Coral, one Runs the Setup and is given a blue square in the middle of the screen asking which progs you want. Word processing loads as normal, but coming back to the screen, clicking on QuickView Plus just makes the whole thing blink, and no install occurs.
The funny thing is, when using the compatibility mode, it gets to the setup file, and just blinks. Blinkin' program.
