As I said for me they behave differently. What can I say... I just wanted to offer the other user a suggestion what to try.
If this happened to you, wasn't because the "two" ( there's only one ) programs are different, but because something else, which might be things like:
- the antivirus working in an heuristic mode and doing different things depending on "behavioral patterns" in the program, and for some reason assumed the program with the reduced interface was more "dangerous" of the one with the complete interface, maybe because it starts download things automatically while the other doesn't.
- the local download cache being active in one session and not in another one. we clears is at each start in the current version but, maybe, this might resulted in a difference in speed in a previous version, just because they programs were run at different times.
But the program is one and the same, that's for sure.
