IE 7 issue in admin

I have been updating my products using IE6 for a couple weeks throught the admin progam/attributes controller etc. I was instructing another user how to do the same but they were using IE7. They stated after making the change and hitting update nothing happens. I thought they were nuts so I tested on my other workstation that has IE7. The same thing happens(nothing). The two modules I noticed it so far is the attributes controller when changing just an image and hitting update. Also when perfoming a change in my product. I am using Zencart 1.3.7 As stated above I have no issue performing this in IE6. I also waited a day to see if it was some kind of issue because we both were logged into the admin at the same time.

Thanks in advance.

What version was being used with the IE 7 and what were the exact steps used on changing the image?

There are older versions of Zen Cart where the method of adding/changing images cannot work due to browser limitations ... newer versions of Zen Cart have added allowances for many of the images to account for this ...

Step by step as in click for click account of exactly what you are doing when things are not working would help ...

I am using Zencart 1.3.7 - If I go to attributes Controller, choose the product I would like to change under the category. Go to the attribute that I would like to change and choose Edit. From there I go to Attribute Controller Swatch and change the picture (already uploaded to server). I choose no to Overwrite existing image on server. Leave the Delete Image button on No. Go to Update and save changes and click the Update button. The screen does not change. There is not an error displayed and no "activity" in the broswer.
This also happens under Category/product when I edit the product and change the image as well. I have not had an issue with IE6. Also this has been tried on two different workstation not located in the same building.

Thanks

There are a number of issues in v1.3.7 ... v1.3.8a handles much of this in a better manner ...

In addition to this, there are many bug fixes and changes ...

Not sure if I can upgrade at this point. Zencart is loaded on the service provider.
