[Eeglablist] pop_rejcont bugs

[Arnaud Delorme]

Dear Tasha,

That sounds strange. Would you mind to 
1. Download the latest EEGLAB https://github.com/sccn/eeglab
2. Remove all EEGLAB from your path
3. Add the new version and start it
4. Load the dataset that causes problem
5. Apply pop_rejcont form the GUI to reproduce the problem
6. Make a video of your screen for steps 3 to 5
7. Send us the video and your dataset at eeglab at sccn.ucsd.edu

Cheers,

Arno
