If two or more imagas are loaded while the plugin is active, the focus is always in the ImageStatistics plugin (due to a repaint?)
I did the following:
- open two arbitrary images
- open the imageStatistics plugin
- select one node, the statistics are calculated
- I select both image nodes and press del to delete the images. Nothing happens because the plugin steals the focus from the DataManager.
- closing the plugin leads to the desired behaviour, I can delete both images with keyboard interaction again.
I tested in with MITK 2016.11 Release in Windows
BTW: In the help window of the plugin, MITK Measurement is the title. And the Troubleshooting section could be removed as it is empty.
