Re: NSTableView issue

[Fred Kiefer]

Hi Andreas,

did you have a look at the mail that Quentin send to this list less then
a week ago? He addresses a problem coming from a similar question you
send to this list previously. I hope that today I have time to implement
what he did suggest, perhaps you could check in parallel if this also
resolves your current problem.

Cheers
Fred
