I've found that is doesn't do it all the time
and only when I have multiple tabs open close two or more
then try to open a new tab.
And only then when I attempt to open a new tab within 60seconds
or so of closing the last one, then instead of a new tab based on the
link I right clicked it opens the last one closed.
It only happens a bit more than half the time.
And yes it still does it even after rebooting...
This is something I only just noticed and I thought I was at fault by clicking
on "reopen closed tab" by accident instead of clicking on "open in New Tab"
It is not a major problem but it is annoying to have to close the unintended
tab and try again.
So far the intended tab always opens on the second attempt.
Someone on another forum suggested it was a wireless mouse problem
only problem is I use a WIRED (Logitech) Trackman wheel mouse.
It is my considered opinion that if I use a wired mouse I can find it at one end of the wire or the other, I've previously lose wireless mice)
