[WriteLog] Intermittent garbage keyed [Was: SSCW 2010 K0HB]

[Radio K0HB]

The computer in my case has an Intel "i5" multicore processor.  The OS is 
Win7 64-bit "Home Premium".

In my case, the only cure was to reboot the computer.

Closing Writelog and restarting it had no effect.  Closing down "router" and 
restarting had no effect.  Powering down microKEYER-II and restarting had no 
effect.

I'm not enough of a guru to understand the significance of this, but......

.....on a couple of occasions when I was trying to close/reopen Writelog, 
one or more of the dropped characters might spontaneously key my rig during 
the interval that WriteLog was closed down.  That suggests to me that the 
"delayed" characters were malingering "somewhere in the OS" between WriteLog 
and the USB port attached to the microKEYER-II.

When I transplanted an old Pentium 4 running XP the problem completed 
disappeared, using the same version (10.81f) of Writelog.

Just speculating ... I wonder if this is a thread switching issue
in WriteLog or the compiler being used to make it?  Is everyone
who experiences the problem using a multi-core processor or one
that supports hyperthreading (an early version of parallel processing)?

The randomness, load sensitivity and apparent delays sound a lot
like thread blocking and out of order execution.
