Dan and Marcus (from another thread related to this),
I'm trying to do what you say, but I get an error when using
*"{0:.3e}".format* in the formatter field. The default value (0) is now
formatted properly but it won't ever update and in terminal I get the
following error
Exception in thread Thread-8:

I also get this error whenever I double click the QT GUI Label in question:

Am I doing something wrong?
