--- Comment #28 from Roderick Colenbrander thunderbird2k@gmx.net 2008-01-07 16:35:48 --- On a sidenote RenderTargetLockMode=readdraw (the default value) won't cause a crash from now on. Further that if-statement which you forced to one should evaluate to 1 now on your system when it is needed (in case of readdraw mode).
