Summary: Weatherscope filtering of combo boxes is broken

Weatherscope uses a text entry field as a filter to eliminate choices in a combo
box.  Under wine, this behavior is broken.  With a blank filter (empty text
entry), no options are displayed in the combo box, though all possible options
should be displayed.  As text is typed into the filter text entry, the options
in the combo box should be updated instantly, which does not happen under wine
(this behavior used to work, but broke under wine in Weatherscope 1.4.x).  If I
double click enough times on the filter text entry, the combox box does
eventually update.  Also, If I click another element on the dialog, and then
click back to the filter, the combo box will (usually) update.

As an example to reproduce this bug, run Weatherscope, and click on the product
menu and select New Radar. (This menu may be hidden by a black bar due to OpenGL
child window clipping issues, but click around enough, and you can find it. I
also find that alt-tabbing to another application and tabbing back will make the
menubar visible.)  You will see an empty text entry field labelled "filter" and
an empty combo box labelled "site" which should list _all available_ radar
sites.  Enter the text "ok" into the filter should cause the combo box to show
only those radar sites that contain the text "ok", but nothing happens.  Some
combination of clicking on the site combo box and clicking back to the filter
text entry or double clicking the text entry should cause the combo box to
eventually update, showing 7 different radar sites available in the combo box.
