Same issue as T302147?

I will check T302147 and report back

It may be the same bug but my experience differs in that it happens to me after a copy-paste and possibly differently after cut-paste of simple text from within the open edit window. When the cursor jumps it cannot be persuaded to stay in the right place for further editing if that editing includes a shift key as the first keystroke. I have to add the text at the top and later cut and paste it to where it should be. It is happening on Firefox with both windows 10 and 11. Once it has started, I have not found any way to make it stop other than cancelling the edit and starting again.
It happens with the new section tool (A new way to start topics...) and with the reply link.

As a temporary workaround, you can turn off Enable editing tools in source mode in your preferences (and switch to source mode if you normally use DiscussionTools’ visual mode). It’s a more bare-bones experience, but it should be free of this bug (or if it isn’t, that’s the fault of Firefox or Windows, not of DiscussionTools).

@Tacsipacsi, thanks for the suggestion. I generally just create the new section title, add content until it goes wonky, save and continue editing using the regular editor which works fine
