I'm having a problem I can't find a solution for anywhere... All of the sudden, out of the blue, my excel will not let me fill cells with color (other than yellow) or change the color of the text in the cell (other than red). It seems like those two functions just froze on the colours I had them on and will now only let me fill cells with yellow (and not unfill previously filled cells unless it is to change them to yellow), and same for the text, which is stuck on red. The really strange thing is that it is not just a problem with the dropdown options in the formatting toolbar, but also if I go to format the cell and do it in the pop up menu - the little window appears as normal but the drop down menus to change colours or fill pattern simply do not drop down. Has anyone else had this problem? Anyone found any fixes for it? I have tried restarting excel, restarting my computer, opening a new document, sending my document to another computer (on which the fill and text color options worked fine), all to no avail. I'm utterly perplexed. I really wish to avoid uninstalling and reinstalling if possible. I am running Microsoft Office 2011 for Mac on Mac OS X 10.5.8. Any help is appreciated!
