At least it isn't just me.  Sometimes I think bugs/bad features pick on
me.  While annoying, I guess it is harmless.  It just seems that as long
as it has been doing this, someone would have raised the hood and looked
to see what is causing it and how to fix it.  Strange that something
weird like this has been around so long. 

Thanks for the reply.  At least I know I'm not alone.
