Since I read your��email, I've noticed now that an image when opened ignores my first click (right or otherwise). Using the latest Pharo Launcher with Pharo 703 images in Windows Subsystem for Linux (Windows 10). It's very easy to just click again, so I never really noticed before. But it is mildly annoying.
At first I was thinking it was an XWindows focus problem (under Windows 10). My tests show that keyboard events go through (e.g., I can use the arrow keys to move selections around), but the first mouse-click is ignored.��
