Why won't Smilies appear when I click their button.
This sometimes happens when multiple windows are open to P-T and the window to which you are trying to add the smiley isn't the one used to open the smiley list. Close the non-functioning smilie list and open a new one and you should be able to use it..
Also note that smilies are always added at the end of your text rather than where you placed the cursor.
