Selecting the sort by 'None' solved the problem for me!
Hope it helps.

yes ingiulio is correct but he could of gave you a bit more information. When you select the paper clip(attach files) icon the window comes up where you can see your files there is an icon to the side of where you can change the view it looks like 2x3 small squareswith an arrow pointing down to side of those squares click on that and change the option to none and that will solve iur problem as it did mine

Okay I had the same problem but I figured it out. When you go to choose file, all the links are greyed out. Use two fingers simulatiously and click down on the file you want, then choose "quick look" from the option menu. This will open a preview of your document and make the open button usable. Close the preview, and then select the open button.

The site I was trying to use says it only supports IE, so maybe that is what causes the problem.

Hope it works for you!

I have a similar problem: if i try to browse my mac from any browser o try to attach a file to a mail browsing it instead of dragging it in the mail the sistem freezes. Firefox and safary freeze instantly with few secds delay, the circling wayting ball keeps turning infinitely, so the only way is to force the exit. I can't find a solution. I tried emptying the cache, no change. I disabled all the firefox adds on, non change.

It wasn't like this befor maverik upgrade, I don't recall if it happened immediately after of after a while.

Please help me on this.

Just double click to select file, which you want to upload. Single click will not work.

Cheers.
