Hi Ralph,

Yes, I do recompile my program as I am running it directly from Visual Studio,
i.e., not a compiled exe version. What puzzles me is that if do exchange the
libcurl dll, my program reports that *no* libcurl dll is found, even though the
file is in the exact same folder and has the exact same file name. If the newer
version, however, is not compatible, I would expect some sort of other error
message hinting at the incompatibility.
