Tested quikly and seems that border problems and gui refresh problem is now gone??
Now my 68040 machine "officially" renders amiga.org faster than my 68060 machine.
Amiga.org is rendered 29 seconds with 68040

, and 31 seconds with 68060. Reloading page and both renders it 23 seconds. Restarted browser and amiga.org was loaded 27 seonds with 68040 and 29 seconds with 68060.
Amigaworld.net is still loaded faster with 68060 15 seconds, and 68040 20seconds.
I haven't had problems restarting browser,except that first version wich has working java.
Restarted browser some 6-7 times, no problems with it.
