I am working in Adobe Photoshop CS6 in Windows. Periodically I'll be typing text and the entire text will just disappear. It has the appearance that perhaps my "text box" is too small, yet I don't see where there's a setting for such a thing. If I backspace, the text will come back. It's like it's just too many characters for it. There's plenty of room on my canvas. Likewise, if I change the font size, it disappears. Any ideas?
Are you using paragraph text (dragging a text box before typing)? If your text box isn't tall enough, all your text will disappear if the vertical size is too large for the characters to fit. Likewise, if you type beyond the horizontal boundaries, Photoshop has no place to flow the extra text so it appears to disappear. You should see a tiny plus sign in the lower right square of your text box indicating hidden text. Just drag your text box larger with the text tool to give the text room and you should see everything you typed.
It is easier to destroy than to create.
More fun, too.
