This is a little hard to explain, but if I go back on some text and press space, it doesn't move the whole text it just replace the character in front of the place where I want to put space with a space. How do i stop it doing this?
This is basically making it almost impossible to fix code.
I have spent a little while fiddiling around in notepad++ but nothing seems to be doing anything useful, I am pretty sure its recently become like this, but I haven't used it in a couple of months.
PS. it is not just if I put a space, but any letter or number.
Below is a link to a youtube video that showcases my problem:
Sounds like you've pressed the insert key on your keyboard accidentally and switched to overwrite mode. Check the bottom right corner of the screen - does it say INS (insert mode) or OVR (overwrite mode)?
Try pressing the insert key again to see if it fixes the problem. Alternatively, you can toggle overwrite/insert mode by clicking on the OVR or INS in the lower right corner.
