There I was blazing away at a drawing due in moments and to my surprise my command lines stopped being written as I typed in commands. Somehow somewhere, I must have changed the settings but I could find no thread of evidence to that effect. Does anybody know why I can't see my command lines anymore? the space and the cursor is still there bu there are no words, no numbers, nothing. Black on black. The letters are supposed to be white but they are not there.
