Secondly, without warning Polish Programmer's kicks in from time to time causing me to type unwanted brackets and puctuation marks in place of the Polish accented letters shown on my Polish 214 keyboard. I can fix this manually but it's a pain in the bum. Is there any way toto permanently delete, expurgate and kick out that useless and stupid Polski Programisty?
It happens to me all the time. You just accidentally push shift + ctr. It's a key shortcut to switch between the keyboard format. Look for a way to disable it in control panel
For one the calibri font which I have never used, disilike, have no use for and never plan to use for some reasons kicks in whenever I click on 'clear formatting'.
You mean in your browser? That might be a virus, but it might be also that you change something in browser options I suppose. Look for option domyślna czcionka.
