When selecting troops the cursor comes up as a hand I take  to the slide button and there is a several second delay before anything happens, the cursor changes to an arrow then to a spinball and finally back to a hand then it works. This is a repetitive problem which I have notice only in the last 36 hours. The rest of the machine is fine and it is not a cache issue is this occurs from startup. The games has become effectively unusable. I have not applied any Apple update in the last week so is not an OS issue.
