Yes, that is what happens to me, too when attempting to view additional pages in iMac section.
Of course I'd attempted to reply elsewhere to a different ASC section; and found my effort most
difficult with short windows of opportunity (timed-out too quick, and loaded slower, also) there.
So perhaps this single issue should be reported. At near 3:40 AM in my vicinity, I'll not likely be
one to do so; since sleep is a higher priority after mucking about with other issues here tonight.
You may be able to find older posts by accessing thread content from within your user profile.
That's how I find most of the old ones; and have several windows open whilst doing so.
In any event...
Good luck in this matter! 🙂
