Theme Fixed & Axim X50v arrived!
Wee, it seems that somewhere along the line the theme download was being cached from my hosting – it turns out I had already changed the right attribute but when I edited the theme on the phones memory stick, only one of my changes was saved..
The attribute in question is Popup -> Highlight -> Background Colour
When I arrived home after work I was pretty chuffed as my Dell Axim X50v has arrived.. I promptly updated to the latest ROM image and downloaded SE_VGA to get true 640×480 resolution.. you can see why they don’t enable that res by default though, everything becomes absolutely miniscule on such a small display
