I’d like to report a small problem with the editor.
If you go to the last line and delete the last character of the last line, then attempt to type some new data, it will not appear on that line. Instead, it will appear at the end of the previous line.
Unless I am mistaken, that is definitely not WYSIWYG. At least not to the best of my recollection.
By “editor” do you mean the Reply to Thread box? Because I can’t reproduce your error. Deleting the last character and then retyping starts exactly where I left off. Same with the Quick Reply box.
Neither is WYSIWYG in the first place, so you may be referring to something else. Could you be more specific?
ETA: I saved the post and then clicked on the Edit button. Nothing wrong there either.
I wasn’t able to reproduce it either.
What OS are you using and what browser?
You could also check UserCP/Edit Options/Miscellaneous Options and look in the drop-down box to see which Message Editor Interface you’re using.
Although I think the full WYSIWYG only kicks in on the Reply and not the “Quick Reply,” so this may or may not apply to your situation. But look at it anyway and see if that makes a difference for you.
The editor is, sort of, partially, WSIWYG (Quick Reply box too), if you click the little square button with an A and an A in it, to the top right of the message box. However, I still can’t reproduce Charlie Wayne’s error when using it in that mode.
Huh. I thought I’ve clicked on all the buttons to see what they do. Anything you don’t use regularly becomes invisible after a while. It’s the curse of Word.
Note that the WYSIWYG editor feature is not available in Chrome. That button doesn’t appear, and my default setting in CP is ignored.
I’m looking at this thread using Chrome and the Quick Reply box has quite a few of the editing tools right on top.
Looking at the “Advanced Settings” Regular Reply window, I’m seeing a more detailed set of editing tools as well.
My UserCP Editor settings are on “Enhanced Interface” and I believe that’s what the system is showing me here.
Still can’t reproduce the problem.
It’s been a long time since I had WYSIWYG, but if I remember correctly (and based on the generally accepted meaning of the term), if you select something and tell it to be in bold, and you see the [NOPARSE]tags[/NOPARSE], then you are not in WYSIWYG mode. And I’m pretty sure you aren’t in that mode, since Chrome doesn’t support it. It has lots of editing features enabled, but that one vanishes.
Previous threadabout Chrome not having the feature, confirming what Irishman says above.
Now that I think upon it, I rarely use a lot of extras in my posts anyway, so it’s not a deal to me. Amazing what you don’t think about when you don’t use it overmuch. I tend to be more focused on trying not to make a typo, which usually means of course that’s exactly when you do. 
Yes, Irishman is correct. Sorry about that, didn’t mean to misinform.
Upon some research it’s not so much a Chrome problem but an actual bug in vBulletin. And it’s not resolvable in the current version of vBulletin on this board.
I do not anticipate an upgrade to a higher version of vB any time soon, if ever, so I’m afraid we’re stuck with this nonfunctionality.
Not seeing it myself.
I just launched IE and logged in to try this…didn’t see the issue either.
I’m wondering if the issue the OP saw had something to do with word wrapping across lines.
I don’t know which browser Charlie Wayne is using, or if it makes a difference.
It could also be accidentally hitting a keystroke like an up arrow when he hits delete.
