I presume most NOF 11 users a far wiser than me, but I thought I'd post this
just in case anyone else missed it.............

A couple of my larger sites, when opened in 11, were becoming perceptably
slower as the weeks went by.
One of 11's new features is being able to have more than one page (tab)
open - very useful. But I didn't realise this feature carried forward, i.e.
if you have six tabs open when you close the site, those six tabs will
reopen ready to use next time you open the site.

By the time I realised what was happening, I had 177 pages open in one site,
and 131 in the other !!!
Clicking 'Close other tabs' evoked a frenzy of page closing, which when
finished left the program with all its original performance restored!

Now I just remember to close unwanted pages before I
exit..................;-)
