Problems with IMCROP (r2012a)

Hi,

I just installed MATLAB 2012a on my computer 2 days ago. I do a lot of image processing and everything was working perfectly. This morning, I tried doing the imcrop function for the first time in my life and so I did exactly as the sample shows, literally copy and pasted it, and I got an error about cmenu being undefined or unknown. I also then tried it with the image I was trying to crop and got the same error. I am not sure what is going on and would appreciate any suggestions on how to fix this!

Here is the full error report returned to the home screen:

---MY CODE---

 I = imread('circuit.tif');
I2 = imcrop(I);
imshow(I), figure, imshow(I2)

---THE ERROR---

Undefined function or variable "cmenu".

I ran the code on R2012a and it ran fine. Type "ver" in the command window and report back here what you see (you can cut out your license code if you want). Or else call the Mathworks and ask them.

It turns out the classic restart your computer did the trick! haha thank you though!
