how to change the font of stacks title bar?

[Tiemo Hollmann TB]

Hello,

Still trying to workaround the title corrupt bug.

the textfont in the properties of my stack is empty. Which font is taken? Is
Tahoma Revs standard, if no font is specified?

When changing the textfont of the stack the font of the titlebar seems to
stay, as it was - probably Tahoma. Can you change the font of the titlebar?

set the textfont of the title of this stack to "Tahoma" doesn't work, any
other solution?

Thanks for any hint

Tiemo
