Assalamoaliekum!!

I don't know if it visible from the text, but when I try adding a thread or try to contributing to an existing thread. the message box doesn't allow me to have spaces for lines and start a new line for new paragraphs etc. could someone please help me on this issue of how to get over this, i use two computers and on my other computer i don't have this problem but the one i am using currently it doesn't allow me to put spaces in my text. I can't seem to solve this problem?
