This looks like a problem triggered by the new "native" 1.3 browser.
Could you test with the latest trook revision (Rev: 68)
which will always use the internal (simple) browser for now?
Please also note that you might need to uninstall/reinstall Trook via
adb -- the current 1.3 softroot image
has some issues with re-installing "pre-installed" applications like
Trook.
