Just had a play around. If I click smilies icon to pick an emote, after picking the emote the box stays open so if I click this reply field to close the box the cursor is in front of the emote which is a pain, but if I click the "X" on the box search field the cursor goes to the correct side of the emote - still a pain tbh.
If I click an emote, then click the smilie icon again to close the box the cursor doesn't reappear so I then have to click reply field again & the cursor is once again in front
So - I'll have to get used to clicking the "X" on the popup to continue.
Wow - 3rd world problems - i.e. ignore me grumbling about nothing
