[Bug] RTF Object

In an app im making, I click a button or a popup menu item and this should change the text to nothing. I tried using set text and set RTF text to "" (which should be nothing). It doesn't do anything. It does however work when I tried start of frame: set text to "blah-blah-blah" Any reason why this is?

you need to select the text in the RTF first to replace with the new text. Think of set text more as replace text, you can set the current selection to the number of characters in the RTF to add text to the end for example.
