Hi, REALLY GREAT Software, but...
in Version 18.104.22.168 Image Editor selecting an overlayed graphic shape does not work properly in any case:
Step 1: do a screenshot, open Image Editor.
Step 2: Create an arrow
Step 3: Create a text box, little overlapping the end of the arrow line
Step 4: activate select tool
Step 5: right click on arrow to open context menu
Step 6: choose menu command "to foreground" ("In den Vordergrund" in german language Version)
Step 7: try to select the text box by clicking on it... it doesn't work. The arrow remains selected.
The "click-sensitive" suface of the arrow seems to be much bigger than its visual representation. I had to move it nearly 1 cm away from the text box to get the text box click-able.
