I've long suspected the Blazer web browser as a primary culprit in crashing my Treo. And so I was really pleased to have found an alternative, a newly released free version of Opera called
Opera Mini that works on the Treo (you can download it via your PC, or on the Treo itself by going to that same URL).
Opera Mini is a Java app, so you'll need a JVM (I am using WebSphere Everyplace Micro Environment). And as a Java app (as opposed to a native Palm app) the menus and controls are quite different to those of typical Palm applications (the menu button, as an example, does nothing).
But, it is fast, it works, and it has yet to crash my Treo! So, despite a rather clunky interface (what is with that obnoxious flashing status bar at the bottom of the screen?), I have made Opera Mini the default browser on my Treo.
I am using the Sprint Treo and since the last update I have had no crashes that I can attribute to the browser. I can't wait until Sprint offers the 700w so I can have Windows and the Flash player.
