Related to task T2359. In a previous revision, the SecondaryButton styled component was changed to show the disabled symbol on hover, however since this button is used in different contexts throughout the app, this revision sets the desired cursor in Send.js, but not elsewhere in the app where the button requires a pointer cursor.

cd web/cashtab-v2 && npm start
in a private browser, hover over the import wallet button on the home screen
the cursor should be a pointer
in a non-private browser
navigate to the send screen
add invalid eCash address or invalid XEC amount
over over the send button
observe the disabled symbol on the send button.
