I'm in the very early stages of writing a program that emulates one of my favorite screensavers of all time. The program simply displays a series of words on the screen, highlighting the appropriate words to spell out the time.
Below is a screenshot showing some sample output. Note that in every case, where a word would be cut off if printed on the current line, QB64 instead drops the word onto the next line. This is perfect and is exactly the behavior that I want, to avoid words being split across two lines. However, notice the second to last line of text in the screenshot below. For some reason, on only this one line, the word "fifty-six" is split across two lines.
Am I encountering some sort of bug here? Maybe something like the letter "x" at the end of the word is falling precisely on the 800 pixel width boundry and it's not being calculated precisely correctly?
Following the screenshot is the entire code, just in case this helps at all.
NOTE: I've done some testing and if I shift words around a bit I can get the error on other lines as well, where I have words that are not hyphenated. In other words, the hyphen in the word "fifty-six" has nothing to do with the problem.
It may also be worth noting that if I change the screen width from 800 to 799 the problem goes away.
