I re-installed the dell-nvidia driver (original with system). Some new behavior observed with bert: tksurfer bert lh pial yields a complete "bert" window (entire pial surface is displayed). However, the lower window "TkSurfer Tools" is not visible. Also, tkmedit bert norm.mgz fails to launch a display, simply returns a command prompt.

I've pasted the screen output for tksurfer below:

Any ideas are greatly appreciated.
