Getting warning about IPTCHECKNARGIN when using IMLINE after 2012a upgrade

I created a gui using imline for selecting range on some figures. It works great and still does. After I updated to 2012a, however, I get multiple warnings whenever I call IMLINE, indicating that IPTCHECKNARGIN will be removed from a future version of Matlab.
I know I can silence these warnings simply by using WARNING but I'm worried that my implementation of IMLINE will stop working on the next upgrade. Is IMLINE upgradable/replaceable without writing my own version (NOT fun at all!)? I'm also a bit confused that Mathworks apparently didn't bother to update their own code.
For what it's worth, calling IMLINE directly from the command line causes the same warning.
Thanks for any help!

We did bother to update our own code. imline in R2012a does not contain any calls to iptchecknargin.
Perhaps you have an old (pre-R2012a) version of the Image Processing Toolbox on your path?

Thanks for the reply, I just got back to working on this project today. Is there a way to force update the image processing toolbox path or can you point me to where I could read about this?
When I use the VER command, I get (along with a lot of other lines...): Image Processing Toolbox Version 8.0 (R2012a)
I also went into Set Path..., reset it to default, saved, then added my paths back, and saved again. I get the same warning.
One option I could do is to uninstall 2012a and reinstall, though this takes a while... I no longer have 2011b installed.
Sorry about my phrasing about 'Bothering' to update your code. I was really surprised at even the possibility that you missed this. I'm glad to know my trust in Mathworks is well placed.

@Craig, the usual trifecta is:
restoredefaultpath;
rehash toolboxcache;
savepath
What is the output from:
which -all imline
? This may point to another clue.

You probably ran the older version after you installed and ran the newer version. Maybe that's why your path got changed.
