	I don't seem to see checkpointing in v2 mfakto windows. Is there any problem? On my side? On the app side? Should I be seeing a checkpoint?

	It seems, that when the task is at about 60% a .ckpt file and a .ckpt.bu file appears. I know the .bu is backup, but why do they appear so late and why does the .bu file have a later checkpoint than the original one? see below: .ckpt: 104864329 73 74 4620 mfakto 0.14-Win: 4595 0 026B80C3 .ckpt.bu: 104864329 73 74 4620 mfakto 0.14-Win: 4515 0 FB8118C9

	Has there been a real answer to this? I'm seeing that whenever BOINC syspends an SRBASE work unit to run another project, the SRBASE unit is resumed from the beginning. This is wasted work unless I'm only running this one project. Are there any plans to fix checkpointing so that it works correctly? Thanks.

Checkpoints are every 10min (depends on the CPU speed), the runtime is not saved by the wrapper. On windows you can check the stderr.txt file. You can also check the FAQ

BOINC doesn't show progress correctly and LLR checkpoints itself. For TF, I'm not sure.
