Description of problem:

Had messages about 19 new updates. As normal user, entered password and had the
list presented on the screen, with all check boxes set.

I clicked on display, to open the lower portion of the split window. Starting at
the top, I clicked on the entry, read what it was about, then used the mouse
scroll wheel to move down one.

After reading the details of the last entry, I accidently used the scroll wheel
again, and the full screen message appeared that pup have no updates. The update
button on the lower right was ineffective.

Second test was to do the above, but ignoring all but the last two entries. Same
problem occurs.  System message PUP not responding)


works fine on a restart
