As I'm not the end user with the problem here, I need to wait for feedback. I have passed the patch provided by Andrew to the bug author - when I've got feedback on this I'll be able to provide more information. I think when we've got a root cause for this then it should be simple to verify it on 4.3. -- Steven Haigh Email: netwiz@crc.id.au Web: https://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299
