[Eeglablist] loading Scan 4.3 files

Dear Philip,

I have retested importing 16-bit and 32-bit Neuroscan EEG files in 
EEGLAB 4.512 under Linux (Matlab 7) and Windows (Matlab 6.5) and it 
worked fine. For some reason I do not understand, the last character in 
your file path is not a delimiter (maybe your file is an windows root 
folder?).
For the second comment, I do not know. You will have to send us your 
data file and a screen capture so we can investigate further.

Best,

Arno
