We are unable to re-produce the behaviour in GroupWise client 7.0.3 (8/03/2008). It print one page from the draft message and received message where the Font modified by the code above. The font and size appear to be fine in print out.
However, the code above change the Font to “Arial” but the font size change to “8”, default font size is “10” and font “Tahoma”. Does your font size change when you run the code? May be a bug in the GroupWise “Fontset()” token.
Which version of the GroupWise client you are running (see Help and About GroupWise)? You may need to upgrade the client to latest release.
