Text copy/paste feature not working for me

[Kris Huber <khuber@sorensontech.com>]

I did an install of the potato kernel and selected packages.  I chose
enlightenment and gnome under X11, which I've used before under kernel 2.4.
A feature I use quite a bit,  hi-lighting text with left mouse button, then
middle-clicking to produce a copy of that text, is not working.  I'm not
sure just where to look for that feature.  My suspicion is that my middle
mouse button is not working.  I have a serial mouse from Logitech and I
selected a Logitech mouse driver during the install.  For 3-button emulation
I selected 'no' because it has 3 buttons and shouldn't need emulation.
Under 2.4 a more generic mouse driver was used, I think.  I'm quite new to
installation issues.  How do I try a different mouse driver?

Thanks for any clue,
Kris
