I’m running an up-to-date copy of Chrome on Win 7 home premium 64 bit. My brief foray into BBS on mobile platforms after the update was something of a disaster. It seems I’d make a correction and then post but BBS wouldn’t get the correction and the post would come out word soup or word salad. Since then, I’ve avoided it though I will say that test was far more usable than when it was trying to display the desktop version. Enough about things I have almost no experience on …
For desktop platform, I’ll say it gets worse when posts are deleted.
I can guess when it’s the post deletion thing because the address bar will show a higher number than the last post on the thread. Not sure how you’d fix that unless via invisible placeholders for deleted or moved posts.
But even without posts being deleted, it will decide that the last post I read was more like 5 posts in instead of 38, etc. In short, whatever counter you’re using for last-post-read may not be getting updated consistently. It seems to be off by at least 10 when I run into that. Not sure if that helps from a troubleshooting perspective. When a post is deleted, I can understand the conundrum. In other cases, I have no idea why it would lack consistency.
Again, that stuff I’m about 90% sure it’s not really that resolvable within current web frameworks. Whether or not it can be resolved, a permalink in the frame would be a big step forward.
