Hi Guillaume,
I am not aware of that problem. I know the was a performance problem
with the early 1.1.* releases for the status of single files.
Can you tell me more about your working copy and your system? (number of
files etc). Status is very dependent on disk cache status. Rerunning
status gives normally much better times.

The difference is not changed file but ignored files.

Thats interessting. The difference is only the amount of output.

I would normally not think so. I am calling the same function. In the
callback the Status object are created.

All those and msvcrt.dll. Use the Microsoft tool depends.exe to detect
all required dll's. You can download it from the Microsoft web page.
