Windows 7: When selecting a file, folders aren't showing left of Windows Explorer

Hey there! (Noob to the forums, wasn't sure where to post to begin with. Sorry if it's the wrong subject thread!)

Basically... when I go to "Choose file" anywhere online, whether it be a file or uploading a picture; my folders and C: disk.. pretty much everything on the left side of the Windows Explorer doesn't show up.

I ran a virus scan not just three days ago? Nothing showed up. Re-running another one... and nothing has yet to show up.

The problem is in the purple rectangle in the attachment. (Did the same exact thing when I was uploading this picture).

From where did you download and install that theme you're running? It looks like a theme has corrupted the display window options.

You were right. I fixed the problem later that day... It was the ExplorerFrame.dll
I probably should have noticed and guessed right off the bat, oh well.

Just wanted to say Thank-you anyways!
