Hi David,
i'm using dropbox from fnc cloud pack.
With the very last version i've some trouble using it, so this is valid for version 1.4.4.0
I think (it'm my impression) that GetFolderList is used when you try to load the "root" directory.
When you choose a subdirectory (and as in the demo CurrentFolder is assigned) the proceure call GetFolderListHierarchical in order to load the sub directory you choose.
With last version (2.1.0.0) something change and happend what you're reporting.
I wrote to Bart some days ago and this problem in under investigaion.
[FNC Cloud Pack: UCloudStorageService demo problem with 2.1.0.0 version]
Due the fact i choose to wait using "upload resume" feature, i'm returned to 1.4.4.0 where all works well.
Hope to understand your question ...
Regards
Daniele
