Comment(by neteler):

 Replying to [ticket:973 marisn]:
 > Any map choice drop-down list with scrollbars is unscrollable with mouse
 scroller. User has to click on up/down or drag slider but can't use mouse
 scroller. Also it's impossible to use keyboard up/down arrows or
 PgUp/PgDown to scroll that list.

 Tested again with winGRASS 6.4.svn (r55719).

 Works:
  * (long) map list can be scrolled by mouse using slider
  * (long) map list can be scrolled by mouse clicking up/down slider arrows

 Fails/unsupported:
  * use mouse wheel (API: http://wxpython.org/docs/api/wx.MouseEvent-
 class.html)
  * use keyboard up/down arrows (maybe key binding missing?)
  * use keyboard page up/down (maybe key binding missing?)

 The mouse wheel support would be a great nice-to-have.
