I decided to load themes on my 7250. Ever since then applications haven't worked correctly. So I put the default theme back on. My calculator has one calculator overlaping another and my scroll no longer scrolls in the calendar. I want to know how I can reload these specific apps on my handheld, preferably without losing the info on my blackberry.

the calendar is built into the core applications of the BlackBerry software I would suggest performing a backup using the backup/restore application within DTM and then reloading the applications using the Application Loader selecting to erase everything and do not automatically backup/restore. So in the end you will have a clean BlackBerry with your backup file. Then using the backup/restore application restore only the databases you need. AddressBook, Messages, Calendar things like that

And stop messing with Themes. They mess up your calculator.
