Is there a huge problem with Facebook?

I just reactivated my account after a week of deactivation due to being overseas. Just now I wanted to upload the all at once by clicking the button and then select the photos you want to upload. After clicking it, a dialogue box appears but when I moved my cursor over to it, I disappears. I even restarted my computer and tried again but nothing worked. Not even when I try to upload the photos one by one, all 150 of them. What is wrong? Should I have to wait a while after I reactivated my account before I can upload anything? This is really pissing me off. Any help is much appreciated. Thanks! :)
