Still losing camera cooling when exposing

Some months back I reported finding that under control from SGP, my SX M25C camera would start warming up during downloads. To some extent this isn’t too important during long exposures (though surely it shouldn’t happen?), but during frame and focus, and during bias and flats, the camera is actually warming up a lot. Yesterday I saw it warm from -15C (normal operation) to -4C and stay there. This does not seem to happen with my other (discarded) software.

There was a suggestion that it would be fixed in a beta update but there is a warning that I should not use a beta update until I am familiar with SGP!

Can someone please advise?
