We had some great responses from our post regarding the BlackBerry OS 5 themes bug. There are a couple of fixes that were provided in the comments that are worth reposting.
From BlackBerry Cool reader Jon:
This issue can be resolved, as posted on crackberry.com forums by wiseguy77:
“step1: obviously load the theme step2: do not use the theme wall paper change it! this is where the issue lies. step3: after changing your wall paper to something other than the theme default go to options>themes>open the little blue box to the right of the active theme. now select the layou option and change the row settings from 2 rows to one row then back to two with out leaving the theme screen, and wala your theme will not longer show the white borders when in landscape mode only bummer is that you have to repeat step 3 each time you change themes or reboot you phone as long as the wallpaper is not the theme default i guarantee you this will work.”
Another solution provided by BlackBerry Cool reader Nathan says:
1. In landscape mode, hit blackberry button, select options and change wallpaper from the theme default
2. Back in options, select layout, change to Today mode, save and close out.
3. Go back to options, select layout and change back to 2 rows.
Theme should now work properly until next reboot
Hope your themes work now!
