P: Using a Script Dialog Slider Hangs Photoshop is looping and not responding

The script still fails in CC 2015 on Windows 10
Adobe Photoshop Version: 2015.1.2 20160113.r.355 2016/01/13:23:59:59 CL 1059143 x64

Chris first it not my Script. Its a script not an extension.

This scipt was posted in the scripting forum. In fact the author states that it works in his Mac version of CC 2015. I tested it with the following Windows versions of Photoshop. The Script works as is in version CS6, CC and CC 2014. I had to remove the suspendHistory part to test in CS2. Changed
//app.activeDocument.suspendHistory("opacity", "theDialog ()");
theDialog ();

With that change the Dialog works in CS2 also Only Windows CC 2015 seems to have a problem with this script.

That looks like there is a problem with your script or extension panel.

With CC 2014 there is no Problem

When Photoshop is shown not responding in task manager I seem to be able to make the other scroll bars also to stop functioning and whem I do the task manager just shows CC 2015 loopind a getting 4% of my machines processing power.
