Additionally, we're rather more interested in completing the new cache implementation than we are in fixing this issue. Doubly so as I've vetoed any such fix being applied to the trunk code as it will conflict badly with the new cache work. There have been very few modifications to the trunk code since the autobuilder stopped, so you're not missing out on much. No. The last released version of NetSurf (on all platforms) is version 2.1. Development builds are just that. We make absolutely no guarantees about their stability or, indeed, their general availability. I assume that you're compiling this yourself? Help->About will show you. If you compile it yourself, however, it will not show you the exact SVN revision the sources came from. This information is inserted by the autobuilder. Please ensure that you are using revision 9801 of libcss. NetSurf is currently unable to use anything more modern than that. John.
