Problem posting

[Jeffx]

Hey there! I seem to experience a problem when I'm posting. It doesn't happen all the time, just sometimes.

When I try to type new sentences after I have already typed some, basically this where I'm typing in right now starts to bug a bit. Every time I type a letter, this message field starts to shake, which causes me to have to rescroll back after every letter to check if I didn't make any grammar mistakes.

Do you understand my problem? What can I do about it ?

Thanks in advance
