Some time browser screen can't open. i check other browser application ,its also can not open.

What is the problem...? browser screen is run after restart the device only..

Pls help me.. what is the problem and how to correct it..

From my point of view the problem is not related to your application. It is related to your BlackBerry device. There is something wrong with the device software and data saved on the device.

Make selective (not full) backup with BlackBerry Desktop Manager. After that wipe the device memory and restore backup file back to the device.
