Might be worth a check to see if uninstalling it helps. It did for us!
Thanks for the extra info, I uninstalled that update on one of our machines, and the screen does update now as intended.

In our case, the program will be used by our client's salespeople, so it's probably not the best solution telling them to 'uninstall a Microsoft Security update'. We will probably pass along this information, but they might not like the sound of that. At the very least, though, we can now at least sound like we know what we are doing.

Luckily, it seems that the screen does update if they hit the 'apply' button on my form a second time, so at least I have a better solution until I can hopefully find a more permenant fix. Running my 'updatescreen' function (both moving an item and gotoslide currentSlide) multiple times doesn't work, so it must be something else in the 'apply' section that was doing it. If I find what that is, I'll check back.

Thanks again.
