Oracle E-Business Suite: Help, My Page Looks Funny!

This last week we had a scheduled patch window after validating a round of patches for our Oracle E-Business Suite infrastructure.  We had our Super User team run through their gambit of tests (minimum was primary/critical functions/processes, and encouraged as much testing as possible).

Something that was not caught in this week's testing was an issue with page rendering.  Our non-production instance we think changes often enough (clones, etc), and most users access it so infrequently, that the user's PC's don't cache the page very often if at all.  Production though, showed some ugly behavior:

As you can see from a testing VM - the page doesn't look quite right.

A quick hit of the refresh button, and the page renders normally.  But, this obviously shouldn't be hitting our users.

On my own PC, our consultant's PC's - we couldn't replicate the issue.  I remembered an old issue with a vendor's website from years ago at a previous company, and we had to push out an Internet Explorer setting change to all users.

Changing how IE checked for new page versions to "Every time I visit the webpage" solved the issue then, and we've confirmed for us it's solved our user's troubles as well.  We think it's because the local PC is caching a copy of the CSS file, and a patch updated/changed it.  We'll be pushing this setting out to everyone via Group Policy in the near future.

Thought I might post this out there for folks who run into similar trouble.
