Hello Maxim,

Thanks for your help!

OP wrote that it is impossible to see selection window inside drawing window. Do you have the same issue? - yes, there is nothing when I use the selection tool. You cannot even see the mouse pointer. Unsure if this short video helps?

Have you updated 2019 version with this Update? - I've just downloaded this and tried to install it however it comes up with a warning as attached. Unsure why that is. It's a LT version, could that be the reason?

Do you have this issue in all of your drawings, even newly created? - Yes, all my drawings, even newly created one.

Do you have this issue always? Or only from time to time? - The box actually worked for perhaps 1 hour yesterday and since then it's never been back again. This is the only period of time since using my new laptop that it's ever worked.

Thank you so much for your help!
