I have two questions related to this simple code:

CDFDeploy[SystemDialogInput["FileSave"], 
  Panel[Row[{Button[Text[Style["sav", FontSize -> Scaled[.2]]],ImageSize -> Scaled[.2]], 
      Button[Text[Style["save", FontSize -> Scaled[.2]]],ImageSize -> Scaled[.2]]}],
      ImageSize -> Scaled[2]], WindowSize -> Scaled[2]]

  1. Sometimes, I am getting Internal Self-Test Error. Why?

  2. I am able to scale Button size, Fontsize and Panelsize in the Horizontal direction but not in the vertical direction. How to do this?

  • $\begingroup$ Have you tried multiple arguments for Scaled? -- Scaled[{x,y}]? $\endgroup$

    $\begingroup$ This doesn't seem to be related to deployment to CDF. I get the same error when I cut away the deploy stuff. It is intermittent. The code number is NoteFont2-c-1883 $\endgroup$

    $\begingroup$ The error seems to be related to the use of Scaled too. Remove it from the ImageSize options and the error is gone. Can you live with absolute quantities? ImageSize -> {100, 200} just works. $\endgroup$

(Based on Sjoerd's comments)

It is reproducible using the Panel part only. You need a new kernel and a new frontend to get this message (so a complete restart of Mathematica). The complete message is:

INTERNAL SELF-TEST ERROR: NoteFont2|c|1883 Click here to find out if this problem is known, and to help improve Mathematica by reporting it to Wolfram Research.

I clicked on the link and reported the problem.

The error seems to be related to the use of Scaled. The Scaled manual page states

Scaled can be used to specify scaled coordinates in any two- or three-dimensional graphics primitive.

You can use Scaled to represent objects that occupy a fixed region in a plot, independent of the specific range of coordinates in the plot.

So, you can't use Scaled everywhere. Remove Scaled from the ImageSize options and the error is gone. Can you live with absolute quantities? ImageSize -> {100, 200} just works.
