I’m not sure this is the same issue. I’ve had something similar happen multiple times a day as well, but its not the same as this issue. In that other case, you see no workflow properties window load at all. There is a solution for that other issue which is to click on the parent workflow (not the steps inside) to get the properties window to show up.
In this case, that trick doesn’t work. Also the workflow properties window does seem to load partially when you click on a step. However, it is just the title bar of the window, which looks very ‘short’. I’ve not experienced something like this, myself–maybe I’m not enough of a ‘power user’ though
