Text in some controls seems really buggy, sometimes when I re-open a saved file text has moved slightly or it becomes cut off. Usually resizing the object solves this but it is a pain having to re-size / align things each time you open a file.
Now I'm working in a mockup and I copied and pasted a button. The pasted version does not display the last word of text, yet if you double click it to edit the full text is there. Resizing in this case makes no difference.
Attached screen shot shows the original button, the pasted version and a resized pasted version which are both missing the last word of the text.
