About the left opening, it seems not specific to PSPad in fact. I am new to this Windows 10 machine, and this issue is more probably related to my ignorance settings things right than to PSPad, sorry.
If anybody knows how to get a right-opening menu in Windows 10, i am all ears ... :-) -- <https://forum.pspad.com/read.php?6,70132,70146> PSPad freeware editor https://www.pspad.com
