I don't know what kind of problem I have with posting and It only happen with this site.
Eight out of ten times that I attempt to post, I have a problem with letter "skipping and fluttering".
Really hard to describe but definitely a problem only on this site. Like, right now, no problem at all.
With this vague description, can anyone give advise?

I have been having that same problem off and on lately. Use the "Go Advanced" method. That solves the problem for me.
