Presenter 7 help suggests way to change the Adobe logo on the
playbar. You need to put a custom logo swf file named 'logo.swf' in
your <PresenterInstallLocation>\Templates\. Suggested stage
size for the swf is 47x27. You can always reduce the size so that
the swf is just tiny spec. If nothing is drawn on the swf file,
then the loaded swf file should show up as transparent.
Regarding the fonts, all fonts (name, size, bold, italic,
shadowed) are listed in vconfig.xml. You can choose to modify it in
your published folder for a one-time change. OR you can update the
<PresenterInstallLocation>\Themes\language.xml to make the
change permanent to your installation.
