I wanted to post an error I have encountered with the Build Text Express VI. When I add a variable that is a boolean and then delete it, the text stays and cannot be changed. For example, placing the Build Text.VI, then adding text to be: "Boolean = %bool%". The 'bool' variable appears then I close the dialog and can wire my boolean to the Build Text.VI. If I go back into the dialog however and delete "%bool%", so that the text in the dialog reads "Boolean = ", then exit the dialog and disconnect the boolean control that is now invalidly wired to the Build Text.VI, the result of the VI will still be "Boolean = FALSE" when it should be "Boolean = ", since there is no longer a boolean variable in play.
