Hi, I'm new to Gimp and have been trying to figure it out for a month now. I'm trying to edit color balance/hue saturation in a photo, but it says 'This tool has no options' in the menu box, and does nothing. I've searched online for a possible solution, and have seen suggestions to ensure that under 'image-mode' you should have 'RGB' selected. I've checked and 'RGB' is already selected. So, what do I do?? It's driving me nuts!! Thanks..
