Hi,
For the sake of nostalgia, I've installed Novetus on countless XP machines I've built/obtained (with varying system specifications, as old as a Pentium 4 HT @ 3.2GHz to a system with a Core i5 1st gen), but I've noticed something troubling between them all.
This happens on most of the older client versions, for this example I'll be using 2008M. The Novetus bootstrapper and client itself work great, however as soon as I run a Play Solo map, I notice that all keyboard/mouse inputs completely stop (including capslock, numlock, indicating a system freeze), however for some odd reason I can actually see the player character's idle animation working.
It isn't limited to just this version of ROBLOX, and as mentioned happens on a variety of hardware-- ATI, NVIDIA, AMD, Intel. EventVwr doesn't give me any logs to work off of either. I've installed all the redist's available for XP and I have a full suite of drivers.
