Was fast at first now slow
gtitus09September 20, 2014
Pros
Initially it was fast. Easy to use. Free.
Cons
Not so fast now.
Summary
when I used this the last few days it downloaded files fairly quickly. Now this morning it said it would take 20 minutes to download a 37 MB file. I tried twice to do it and the same thing, so I switched to Firefox's regular download mgr. It took 5 minutes. I don't know why it worked at first and now it doesn't, but oh well. It was free.
won't work with Mozilla 17.0.1

Cons
stooped working with Mozilla 17.0.1 and when I submitted a report to west byte their server crashed before I got a reply to my post. I have been a paid owner of the pro version for many years. this is my first major let down.
Summary
I hope west byte gets this fixed right away, as I never plan to use internet explorer if I can avoid it. my version is 5.13.3.1321
The first program to be installed on new OS Windows.
