GIMP box is missing

So I was going to make a background for fun and I start up GIMP 2.0 and find this… I can’t make a background without the box dialog there. (Where the red box is on the left) I’m on Windows Vista not that it matters. Anyway, how do I get the dialog box back where it was? Like the size of a brush, brush, etc. I already tried uninstalling and re-installing it but nothing worked.

X-out of the program, go into windows and click toolbox tab and it should be fixed. If not, maybe try redownloading it.

Gimp is old! I don’t even understand how it is still alive.
Only on linux it’s still good because Photoshop is not available.
