Installed Leap 42.1 (KDE) + NVidia repo drivers.

One strange problem I found is that when I run Yast and click on "Online
Update" or "Software Management" the next window opens for some brief time
(while it perhaps gathers information on packages) but then closes on its
own (!).

The only way I have to keep it open so I can use it is to click on the Title
Bar while this initial package information gathering until all the fields
and tabs are drawn in the window.

Other Yast sections (like the Repositories and Partitioner) do not seem to
have this problem, but I have not tried them all.

Has anybody seen this?
Thanks.
