It's probably a 'Feature' but the fact that when dialog boxes pop up they don't pause the main screen means that they sometimes pop up in a strange order making it harder to determine what they apply to. I know why it's happening, and may not be easily fixable, but it can be very annoying at times.

For instance, if I loot a treasure on the last move of a unit, the screen will advance to the next champion THEN pop up a dialog box asking me if I want to equip the item, making it not obvious that the dialog applied to the unit that last moved and NOT on the unit now selected and under the cursor.

The worst example was one where I got a pop up asking me if I wanted to do single combat, said Yes, then went through a normal battle, and only after the battle caused by movement went right into the single combat. The normal battle should not have been sandwiched between asking the question and the consequence.
