Get him to do it again, maybe he’ll turn off what he switched on.

Yes! Thank you so much! Normally he just hides the cursor but this was a new and exciting departure.

My cockatiel always used to stamp around on my keyboard and alter these sorts of settings😏

Killed the mouse.....

My Dog once sat on my laptop and the screen ended up upside down but it wasn’t the usual fix, really had to look to put it right. Not as bad as the time DD managed to make everything on my iPhone present in Japanese characters (Kana). It was a long time ago and I was the only one in the family with an iPhone at the time and I couldn’t go through settings to change it because I didn’t know off by heart where it was and of course, well, everything was in Japanese! Had to get a friend to come round and use their phone to find out what to do step by step on mine, had to sort of count key strikes etc to get to the right place. Probably should have just learnt Japanese. 😂
