[Laszlo-dev] Loading lzx file errors

[P T Withington]

I suspect there may be some issue in browsers that aggressively try to  
cache.

I have seen similar issues in Safari 4 with Jira where reloading the  
same page causes just a blank page.

This makes me think somebody (either browser or server) is not getting  
their cache signals straight.
