I discovered an issue with group dispel abilities, such as the Undead Destroyer’s “Devour Magic” and the Night Elf Wisps’ “Detonate.” When you group these units with other types of units and move the mouse cursor over the group frame, pressing the hotkey for the dispel ability (for example, “D” for the Destroyer) causes the mouse cursor to disappear instead of turning into a crosshair. The crosshair only appears if you move the cursor away from the group frame and then back to it, allowing you to select units within the group for dispel. This problem did not exist in version 1.27.
