I know I can hit the X to close a tip when it appears, but the real annoyance is when the tip appears at the top, it interferes with the register if the register is sorted with newest date at the bottom. The newest row or two is shifted down "off screen" until you close the tip, because the top of the register has been pushed down to make room for the tip at the top. When I close the tip, the register slides back up to where it should be, and the bottom rows re-appear.
This isn't a problem when the newest transaction is at the top - the entire register moves down and the topmost transaction remains where you'd expect it to be.
I haven't found a setting to disable the tips but perhaps it's there somewhere.
Thanks.
