Hi Andreas,

it would surely help, if you could report this as a bug on our savannah 
page. Currently there are no automatic mails send from savannah, still 
it will keep track of any changes to the report and bug reports never 
will get lost, which they may on this mailing list.

The problem most likely comes from the mouseDown: code in NSTableView 
and I must plainly admitt, that I don't have a clue what the current 
code there tries to do. All that complicated code there seems to be 
geared at the tracking of columns, which I would only expect in the 
header view and there is never a call to the method 
trackMouse:inRect:... of the current cell, which would fire up the 
combobox. I will have another look at that code, but it surely would 
help if somebody could comment on the intended behaviour of the current 
implementation.
