Problem with display of wxGetSingleChoiceIndex

[Jörn Koch]

Hello wxWidgets users,

we recently moved from wxWidgets 2.6 to version 2.8, that brought some 
changes in the display of certain screen elements.
While working on the code to achieve a display similar to the previous 
wxWidgets version I found that the display of a wxGetSingleChoiceIndex 
changed in size and I'm not able to restore it to its previous size.

According to the documentation the size of a wxGetSingleChoiceIndex is 
150x250 per default. This worked perfectly well with version 2.6. 
Without changing the code, it now leads to a wxGetSingleChoiceIndex 
window with a size of 346x334.

The code:

   wxGetSingleChoiceIndex("Available configurations:", wxString("Please
   select a game for ")+MapName, Choices.Size(), &Choices[0]);

According to the documentation the last 5 parameters are per default set 
as follows:

   wxWindow *parent = NULL, int x = -1, int y = -1, bool centre = true,
   int width=150, int height=200

This hasn't changed since version 2.6.

Even if I explicitly set the values like this

   wxGetSingleChoiceIndex("Available configurations:", wxString("Please
   select a game for ")+MapName, Choices.Size(), &Choices[0], false, 10,
   10, false, 50, 100);

the positioning and size parameters are ignored and the window is shown 
in the same way as with the default values.

I checked this problem with Windows Vista and Windows 2000 using VC++ 
2005 as compiler.
Our previous wxWidgets version was wxMSW-2.6.2, the current one is 
WX_2_8_BRANCH.

Thanks in advance for your help!

Best regards
