On the contrary, I want to replace the current behavior with something that makes `invisible' _always_ override `display'. The current behavior is for `invisible' to override `display' in _almost_ every case. In fact, all except one edge case. I simply want to eliminate this anomaly, which is causing me quite a bit of trouble. Here is my use case: I have some text that I want to make invisible, so I set its `invisible' property to `t'. The result: If the first character happens to be an image (or a pixel space), that and only that remains visible. -- Daniel Brockman
