I am not sure whether it still matters, but I have been in the same
situation as you, and discovered that in many situations it depended on the
sharing-status of the directory you try to upload from.
	If it is not shared explicitly, uploading will fail (often).
However, I could not figure out clear and consistent rules for when it
mattered and when not, and in general had the impression that in later
comswiki versions uploading went smoother.

	hopes this helps,
