Here is a small screenshot before further explanation for this minor bug :

So, what happens here ?
- I select an hex where several units are located (1)
- I press the M shortcut : the reachable hexes for the selected unit (the first one of the stack) are highlighted
- I click in the second unit's icon on the right panel (2)
Bug n°1 : the selected hexes is no more highlighted, what can be seen on the screenshot. Anyway, that's microscopic and I would not even have noticed it were not the...
Bug n°2 : if I click on the escape button (the leftmost one, the red cornered arrow, on the tools rows) or press the escape key, I expect the stack to be no more selected for move (that's OK) and the reachable hexes to be no more highlighted, and that's not the case : they remain highlighted.
AMOF, it's mainly a refresh canvas problem because if I use the glider to move to one of the edges of the map and then come back to the incriminated zone, the highlighted hexes have returned to their normal display.
