Windows 8.1 double-clicking desktop icons > default list

Ever since I upgraded from Windows 8 to 8.1, and setting the scaling option, some of my desktop icons behave strangely. If I double-click on, say, the icon for Firefox, it works normally. But if I double-click on an icon that is a shortcut to a batch file, I instead see my default dopus lister. I can right-click that batch-file shortcut icon, and choose Open, and the batch file will run. This also occurs with some of my other desktop icons. I have not yet figured out a pattern to this. At first I thought that the scaling option would make larger icons that would only take a double-click in a certain subset of their area, but experimentation with clicking in different parts of the icon seems not to sustain this theory. I am at a loss for why this is happening.

Any thoughts for further experimentation/debugging appreciated.


If you set Preferences / Launching Opus / From the Desktop to Disable, does Opus still get launched?

If not, do you still find the icons don't respond to double-clicks as you'd expect?

Sorry for the delay, I was traveling and away from my desktop PC.

If I disable the double-click on desktop bringing up the default lister, this problem goes away, and everything double-clicks normally.
