Strange issue with Safari

[eluser]Kenneth Allen[/eluser]
Tested with CI 1.7.2 (latest available) and Safari 4.0.3 (latest available) under both Mac OS 10.5.8 and 10.6 with same results.

Sometimes when invoking an action (via a form submit mutton), the code executes but only the rotating action image is displayed in the tab header; nothing is actually updated on the screen. Stopping the request and adding trace (emit h4 tags with text) causes the logic to actually work, although it reports an error (different depending on whether the trace is before or after the redirect). Once that is done, removing the trace causes the entire thing to work, at least for a while. Invoke it so that it passes through some other logic path and it may exhibit the same issue.

Tried this with Firefox and it did not seem to exhibit this problem at all.

There does not seem to be anything wrong with the code, as once the trace is added and removed it works fine.

Anyone have any thoughts on why Safari alone would exhibit this problem?
