All,
this relates to Beta 13.0.0.26 of Toad for Oracle.
When editing a package I Find (ctrl-F) a routine-name. Works ok.
Then I hit F3 to find the next occurrence. Cursor jumps to next occurrence.
After that, F3 no longer functions.
Unless I move the cursor beyond its current location; then F3 will jump to the next occurrence.
Only to get stuck there again.
