When I create a slider wheel window, the slider button itself appears to be missing. What is the problem?

Synopsis

Slider button does not show up in the slider window

Symptoms

In the slider wheel window, the resolution button appears on the right and the number indicating the current value appears on the left, but in the middle, there is nothing where the slider button should be.

Solution

"This is a symptom that the slider window itself is too narrow. The slider window can be widened by clicking on the left or right edge of the window and dragging the window to make it wider. OSLO will be updated in a future version so that this condition does not occur. THIS ITEM HAS BEEN FIXED IN OSLO 6.2.2a AND LATER VERSIONS OF OSLO. The slider window now has a minimum width so that the slider buttons can always be seen."
