"selectstring" in comboboxes and lists

[Peter2]

I'm not sure if the function "selectstring" in comboboxes and lists works as expected. There are two questions:

a) Selecting entries in different comboboxes and lists
Sometimes the selection is displayed "as selected" (blue), sometimes not.
Some selections deselect selections in other controls, some does not deselct ...

b) The using of the commands

Code (autolisp) Select Expand

    (dcl-ComboBox-SelectString combo_select/main/style0 "Style 0 - b")
    (dcl-ComboBox-SelectString combo_select/main/style2 "Style 2 - b")
    (dcl-ListBox-SelectString combo_select/main/Listenfeld1 "List - b")
has different results, depending (maybe on question a and) on which command  is activated or not.

Please take a look at the screencast here:

and at the attached example.
