I repost my answer because I first sent it using HTML causing it to get 
garbled in the archives.

Sorry!

I don't quite get it when you at first say that 'everything works ok' 
and then say that 'the problem above exists'. Could you be more specific 
please:

1. Could your problems be environment/version related? The application in
                http://personal.inet.fi/cool/operator/BPMDownload.html
uses the grid successfully. BPM runs on Windows XP Home SP2 using Python 
2.4.3, wxPython 2.6.3 and PythonCard 0.8.2.

2. If you mean that the simpleGrid demo works but your program doesn't, 
you should compare them to find the differences. There's bound to be 
something because in this case the environment and versions are the same 
for simpleGrid and your program.

3. "the scroll bars do not work"
In what way? Are they not visible. Are they visible but do not react 
when you click the arrows or the empty space of the scroll bar. Can you 
drag the 'thumb'?

4. "I can not select any cell with the mouse"
When I click a cell once the rectangle showing the focused cell goes to 
that cell. When I now click that cell again the text in that cell is 
selected i.e. is shown with a different background color emphasizing the 
fact that the next keyboard operation modifies the whole text. If I hit 
delete, the text is deleted. If I enter new text it replaces the 
selection. Doesn't your program behave like this?

If you mean that you want the cell value to be selected and copied 
somewhere when you click the cell, you need to do something like this:
 
def on_ansGrid_leftClick(self, event):
        print 'ansGrid leftClick'
        r = event.GetRow()
        c = event.GetCol()
        print 'r, c', r, c
        aCM1 = self.fr.test.items[self.fr.currItm].ansCount - 1
        last = aCM1 / self.columns
        if r > last:
            print 'r>last', r, last
        elif r == last:
            last = aCM1 % self.columns
            if c > last:
                print 'c>last', c, last
        else:
            print 'set text'
            self.components.ansField.text = 
self.components.ansGrid.GetCellValue(r, c)
        self.components.ansField.SetFocus()
        #event.Skip()
