After a long silence, we finally have a new Pinger for Windows. Still not fully optimal, but looks like it works mostly fine. Download and see more info. A major improvement is that this one works also for non-Administrator accounts in Windows. (Admin must still install it, but everyone can then run it.)
We still don’t have a Pinger for Mac or Linux :( contributions would be welcome. (I got a Mac and it would be fun to write one, but time, time, other matters keep pressing…)
