command line

Hello everybody - I recently began using LibreCAD and it's very useful for me, however I really need to use the command line but something is wrong. When I type anything, it is as if after the first character, I press "enter". If I type fast, some characters get through - for example, I type '30,30', sometimes '0,3' gets through. I use LibreCAD V2.1.3 and Windows 10, latest build. I can elaborate further but I HAVE to have command line working. Thanks in advance.

I can't be certain but this sounds more like a keyboard response problem than LibreCAD.
Admittedly I typically don't type fast when using the Command Line but I do sometimes find, on my laptop keyboard, that keys pressed do not appear in any program (e.g. wordprocessor) and typing errors occur that I know I have not made.
