Hi tickmike
It's a mathematical calculation error, usually for rounding or decimal etc
It appears onscreen and not logged in the program which has/had the issue
Dslstats itself does not I believe do any calculations as it's reporting the numbers given to it from the modem (sorry if I'm wrong) but it probably does calculations for the graphs, which is where the floating point error may be happening.
The floating point error is generic term and does not give indication as the where or what caused it. However, it is a mathematical error, ergo has to be caused by calculations
This could be the graphic card, graphing calculations or similar
That said though, if there were a specific bug in dslstats graphing, I would expect it to show on all installation of dslstats where as, if it only appears to happen on 1 or 2 users installations, it is more likely unique to their computer
It could even be that the program needs starting using administrative rights, so it can correctly function due to Windows permissions been different for users/administrators and it's ability to read/write
The above is just a brief outline and others may post more in depth, but a google will bring lots of pages up
The reason for advising a hardwired network is to ensure no interruption to data stream
Many thanks
John
