The right docking area with GBPUSD was set up just like the left docking area, with 3 charts, 1 large at the bottom with 15 minutes and 2 smaller charts above: daily and 1 hour. As I was changing the time frame on the bottom, right GBPUSD 15 min chart, the 2 charts above dissappeared, the bottom chart filled the whole space and all candles, data, drawings etc dissappeared, and the chart is completely unresponsive.
