Okay then, looks like I can discard the last ver 3.54b4 full install of WinMX I downloaded but have yet to install on my new HP laptop. Instead I'll simply install this latest patch/full version (a bit confusing, you must admit, being a patch as well as a full install of the program).
Re. updating my 3.31 version, I'm rather leery coz the oooold laptop on which it's installed is totally full-up with no HD or RAM to spare, running on Win98 SE btw. So, if the newer versions require more RAM or take up more space on the HD, then I'm kaput. I'm operating on just 64MB RAM because my addl 128 stick (2000 laptop, maxes out at 192MB RAM) burnt out, or rather the compartment did, so I'm stuck with just the permanent 64MB stick that came with the system.
