Microwave vs motion detector

Why would my mum's (inside) microwave set off her (outside) motion detector?

My mum had a light with motion detector installed in her back yard a while back. For practical reasons [easy access to electricity at security-light-level] this was installed within a foot or so of her microwave . Obviously with a wall in between (microwave inside, motion detector outside).
But now, whenever she uses the microwave, the light comes on [only during darkness, i.e. when the motion detector is on]. So basically it interprets this as "motion". [after the microwave is done, the light remains on for the customary 30secs]
What could be the reason for this?
(NB I'm not so much looking for "how can we fix this" - she's had a switch installed to disable the light while she uses the microwave. tho if there's sth really obvious please do share)
