The mods deleted a bunch of posts throughout the thread, so there are less posts, but the pages that would be filled if the posts hadn't been deleted remain.
It is worse with tapatalk. Blank pages with no posts.
Stand at an offset position and line the arrow to the 125 symbol in the following manner... Center of arrow to edge/ Edge of arrow to B.
Now rotate to center and you will find the arrow and 125 lined up perfect everytime.
If you still have problems you either have a flaw in your left clicking action or it could be that your screen is not the required 2×1 diminsions.
I hope this helps.
