title: Editing text from outside shoes app overlaps text
body: <p>I am working on a ruby app that needs to update text on the GUI at unknown times. The process I am using overlaps the text with text from the previous edit.</p>
  
  <p>class_text is the element I need to edit. I have about 8 different places in the program that could potentially change the text. Sometimes when the text is changed the previous text does not get removed and instead the text overlaps itself.</p>
  
  <pre><code>$class_text.text = "Nothing scheduled to take attendance at this time." 
  </code></pre>
  
  <p>This project was started by people before me and this is my first experience with Ruby. Thank you for any info you can send my way!</p>
