Should maybe not throw out the baby with the bathwater. What you describe shouldn't really happen - that's meant to be the asynchronous in Ajax - and could well be a problem with our implementation. So I'd go for an optional button - perhaps driven by a general system-wide setting "No-Ajax-Please" which could be used in other parts of the UI as well. > I am experiencing a very high latency environment right now, so it may > be a while before I can get launchpad to work. I had some problems with launchpad last night. I think sometimes it just gets bewildered.
