Thanks for replying, Mitchell.
As far as I can tell, no I am not. I have some custom css that gets pre-processed via the compass process, but I was careful to use em's instead of px values. Even so, the areas where I defined custom css are few and far between. The components in play are mostly default Sencha Touch 2.0.1 components.
I read on a stack overflow thread about setting a META tag for the viewport. Could this be related and/or a requirement?
The related thread is here: http://stackoverflow.com/questions/1...ewport-scaling. The recommendation from that thread was to do something like the following, but I haven't seen an improvement.
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no">
