Description of problem:
Clicking on the "resize" dividers on the package selection table
header(s) (e.g. "|" in  | Package Name | Version ) should allow to
resize the field, but instead toggles the first package selection
checkbox. Wierd, but harmless. Sometimes the default field widths are
too small to read the full version numbers, so would be nice if this
could be fixed.

Version-Release number of selected component (if applicable):
up2date-4.1.16-1

How reproducible:
always
