Left Mouse Button issue

[Karagin]

Okay, I have noticed (in both games) that when using the left mouse button some times allows the AU ran units to use OP fire vs opening the window to tell me some info about the target unit. This happens several times in different scenarios and battle fights. OOBs or year etc... don't seem to be the issue since I have seen it happen regardless of the country or year.

I engage a unit, then after watching the messages about hits doing their damage or not, etc... I will use the left mouse button to check things like how many men did the infantry unit start with and to see what weapons, but instead of the small window popping up the AI ran unit opens fire and in some cases kills my unit or gets in some nice damaging hits. It's random when it does happen, and at first, I thought it was the scenario, but then it happened several times in a random battle fight. I have seen it happen also in SPWW2.
