Thanks for the reply.
However, it didn't work. I even tried deleting the old toolbar and adding a new one in case I messed up any of the properties.
1. Added ToolBar
2. Add Button
3 In ToolBar properties, change value of 'Show Captions' to true (so that the caption on the button is displayed)
4. Click on the ToolBar, select 'Font' and change its sub-property of orientation to 900 [didn't work] and then to 2700 [didn't work]
If it makes any difference, I'm using GNU/Linux. Am I doing it right?
Cheers.
