Okay,
I loaded up Second Life this morning and was unable to use it because I cannot see my mouse cursor on-screen!
It's there because if I carefully move around the screen, I can see buttons lighting up as if the cursor was there, but I can't actually see the cursor...
In an attempt to fix the problem, I re-installed Second Life over the top of the old copy, but this didn't work, so I un-installed Second Life, restarted my computer, ran my system cleaning/registry fixing tools, restarted my computer and then re-installed the latest version of Second Life - only to have the same problem!
Any ideas as to why I can no longer see my cursor, and how I can restore it?
