My issues happen while using the editor properly. Doesn't have to be via copy/pasting into it. It can be just editing a post that was already made, or while creating a post, going back and adding or removing part of what you typed can cause massive issues. Especially if the post contains any type of code formatting, it seems to happen much more often then.
@atom0s refer to number seventeen regarding BBCode... https://forum.tuts4you.com/terms/
It's probably best to select "remove formatting" when copying and pasting content to the editor then use the editors built-in features for formatting.
I have no idea if there are other supported editors that can be used with IPB. I'll make a note to have a look this weekend when I have some free time...
Oh well sorry for the late reply!
I just wanted to do it and expose the methods malware writers use often to create their malwares, I just did in PureBasic since I was working on it and found it's a really great and fun language to work with
And btw you can work with kernel mode from PureBasic also, you can even create your own Drivers, there's a suit that allows you to do that:
Thanks for writing!
