In the data grid, when scrolling up or down, the cursor always stays on screen, keeping one of the rows on screen highlighted. This is a problem when trying to select multiple rows and some of those rows are off screen. Say I want to highlight the first 100 rows in the data grid. Normally, I would highlight the first row, scroll down to the 100th row, press SHIFT, and select the 100th row with my mouse. This is not possible in Toad's data grid. If I highlight the first row and scroll down to the 100th row, the cursor stays on the screen and highlights the first row on the screen when I reach the 100th row. So when I press SHIFT and select the 100th row with the mouse cursor it only highlights from the first row on the screen to the 100th row.
WORKAROUND:
Highlight the first row you want to highlight, then press shift and the down arrow key until you reach the last record you want highlighted.
STATUS:
Waiting for fix to be released in a future version of Toad for Oracle.
