Thank you Pinniped,
I'll follow you guide and try to build the LILO. However, I have just encountered another problem, I have just had my flashplayer plugin upgraded. Problems happened now that, browsers (firefox and seamonkey) closed itself automatically when they come to animated pic and flash media.
Similar happened before but was fixed when I reinstall a lower version of adobe flashplayer e.g. ver 6 or 7 (now is ver 10). However, it didn't work this time. When I remove the libflashplayer.so, the browsers seem ok and wouldn't close itself but with all the animated pic and flash media disabled. Could you give me some hints on this. Many thanks in advance.
