everytime i boot into OSX via rEFIt, when i try to boot again later, from restart or turning on, rEFIt dissappears, and i can't access GRUB (for booting Ubuntu and Crunchbang) anymore, unless i run on OSX, via terminal, "bash /efi/refit/enable-always.sh" over and over again - i supposed that enable-always.sh would be enough and lasting to never mind about this situation, but the fact i need to run it all the time is quite annoying - how can we fix this? thanks!
