Anyone know of a way of stopping a Mac running an application on a remote 
mounted volume when you double-click on a document, and the application is 
somewhere else on a LAN or WAN.

I often mount volumes elsewhere in the country over our WAN, and when I 
trigger the application, the Mac cheerfully runs, for example, Photoshop 4 at 
the other end of the UK. I suppose I should be impressed that it works at 
all, but once it's triggered the application, the only way to stop it is to 
re-boot, or wait the age it takes to run the program so that I can quit it 
and mount the correct Jaz disc.

Help, anyone ?

TIA
