Hi cyberunner and Welcome to CDF:
Could you take a screenshot and post the image so we can see it? Have you tried reducing the point size and/or changing the font?
[B]Update:[/B] I was just in NeroVision 5 (part of Nero Ultra 8) and could not duplicate your problem. The buttons expanded as more text was entered.
Besides a screenshot, more information could help isolate the problem (e.g. what Nero program are you using and what version)?
