Toad for SQL Server 5.0. does not support Mouse Wheel Up, Down, Left, Right scrolling.
The Mouse-Wheel scroll Up/Down works only if I click on the drop-down arrow of a cell and then click "Cancel" (too many things to do before it works).
The Mouse-Wheel Left/Right does not work at all no matter what I click on.
WORKAROUND:
None
STATUS:
Waiting for fix in a future release of Toad for SQL Server.
