Same problemon my Dash
I am having a similar problem on my Dash with some web pages not loading all the way. For example, at the xda-developers web site they have a page that has WM5 tweaks. The page loads completely on my SDA but stops loading at about 78K on my Dash. I have to press the STOP key to get the loading process to stop. Only a small portion of the page then displays. Never had a problem with any pages displaying on the SDA.
