Can "DROPBOX" cause problems?

Hi Experts---

I installed the DropBox utility last nite.  I registered for an account and closed IE.  tried to get back on the Internet later and Nothing happened.  

I really am not sure and cannot blame any one utility.  I was very busy on my computer yesterday so it could have been anything I did.

Anyways,  I like this Dropbox idea but am not too sure about it.  I wan to use the free 2GB version to try it.

So---The QUESTION IS----Can anyone who has experience with DropBox enlighten me about the utility?  Whether it is known to cause issues?

I got all the info I need from EE Knowledge Base. I am good to go, so I will close this now since nobody answered in almost six hours anyway.

there was lots of stuff on the "DropBox"  App.
