[Mono-winforms-list] Bug? DataGridView on Mono Crashes (or locks rather)... does not occur on Microsoft platforms

[Stifu]

I know a lot of fixes for DataGridView went into Mono after 2.2.
See: http://i-nz.net/2009/01/15/datagridview-revamp/

Maybe you could check Mono 2.4 RC1 and see if it makes any difference.
Here's the openSUSE repo:
