what does it mean when synaptic won't install
 

trying to upgrade a prog using synaptic. i select the prog hit upgrade it takes a second then comes back with nothing selected. does anyone know why this would happen?

It could be that according to your source list you have the most up to date version.

but it shows that i have kde 3.1.4 and 3.1.94 is availale and the upgrade option is available when i press it, it takes a second then comes back with nothing selected fo install

Have you tried closing Synaptic, going to a command line, su-ing to root, typing apt-get update and then apt-get upgrade synaptic? (I don't have Linux atm, so I am guessing at the commands)
