Time Series Plots can not be saved

[TonioF]

When you have created a time series plot, a right click into the plot will give you the option to save the plot. A dialogue opens, the saved file, however, is empty (also, the suggested file name "Download.png" is poor). Likewise, copying the image from the context menu will give you an empty image. The option "Save as Image" in the bottom right corner of the plot does not even bring up the save menu
