I have an inkling what may be happening here and I did see it myself once or twice a few days ago but the problem seems to have cleared for me - I can't make it happen any more.
Can anyone see any common factor when it happens? Is it for example when more than one browser window is being used to browse ARRSE, or in long messages where there is a comparatively long gap between starting the post and actually posting/
Has happened to me a few times very recently, once or twice yesterday.
Short messages, either "Quick Reply" or "Reply With Quote", in response to short messages. Nothing lengthy.
Also, putting a pic in reply seems to be playing up; once URL pasted in and OK pressed, occasionally long, long pause before it works or, occasionally, seems not to work. Must repeat process until it eventually works.
Maybe faults have something in common? (Other than me being shite with computers.)
Added: Sometimes it appears picture not uploaded, but then it appears in message anyway...
Thanks. What I'm trying to do is work out what is different on the occasions when it happens. One option is just to disable it altogether. We managed without an automated check for years and I think it might have saved me from losing a post once since we've had it, buy irritated me many more times.
