Since I've updated to r77, I get a code dump anytime I try to copy from SD card to an SMB share. No problems going the other direction. I even reverted to r74 - same problem. Anybody have any ideas?

It's still in the Alpha phase, the earliest usable stage. Tell the creators about the bug, it will be helpful to them.

Thanks for the reply. I plan on filing it as an issue on their website as well.
