Channel Map loading function error

[msvdgoes]

Encountered a problem (easily solved) when trying to load a config file for the channel map. After adding the FPGA (everything great, 64 channels on port d found) and the channel map node, It did not automatically select/highlight port "d" on the channel map. If you find "a" highlighted on channel map and click on the icon to load a config file, you receive such error on the terminal window: X returned BadValue (integer parameter out of range for operation) for operation X_ConfigureWindow. The whole open ephys window is then frozen.

To solve it, just clicked on the appropriate port on channel map (I had to select "d") and then I could proceed loading the config file.
