Yes- by default, only Opera and HTC Album will rotate, so without the add-on rotation program that's all you will get. Not sure about the 'phone viewer' you mention- there are 2 picture progs on HTC devices- HTC Album and the default WinMo Pictures & Videos program. The latter won't rotate as supplied.
I'm a little surprised you can't find a setting to give tolerable text sizes. In PIE have you tried Menu/View/Text Size/Largest then Menu/View/Mobile (then Refreshing the page). For me, this gives the biggest text and is readable, though I do use an XDA Flint which has a 5" screen!
I don't condone site 'poaching', but the other site I moderate on, as in my sig, has a little more experience of the Diamond2- it might be worth asking advice there
What happens in opera is a time lag on rotate, so it will turn but takes about 30 secs or so, and sometimes needs a shake to persuade it to flip
I have found those text setting - but they make no difference, its still an unreadable size even on largest (and I have got others to check, so its not my eye's - lol). I've also remembered to click on the tick to save the settings...... The text size in PIE is fine, and readable on default settings by the way.
By *photo viewer* I meant the HTC Album - sorry about that
- nothing rotates in that. Just to confirm, I get to it by opening the camera then clicking album? I am possibly doing something wrong as I find the diamond 2 more complicated that other WM I've had!
I'll tootle over and check out the other forum....
Thanks for your help with this - and sorry if it turns out its me being numb!
