Problem with "New Rule" button disappearing for Conditional Formatting

I created a Business Objects (Version: 14.1.4.1327) report and when I began applying formatting to that document, I clicked on the New Rule button to apply conditional formatting. My browser locked up and when I went back into the report after restarting the browser, the New Rule button is no longer there.

1. Any ideas for why the New Rule button disappears and how I can get it back?

This is not the first time I've had to re-create the report to "get" the New Rule button back, only to have it disappear again.

This seems to be report specific (and not role based, nor Java based), as I can create a completely new report and the New Rule button appears in that report (I just need it to stop disappearing or a way to easily make it re-appear without re-creating the report).

Any thoughts would be great.

Thanks!
