Dragon Professional Individual 14 - what I have found so far

Since installing Dragon Professional individual 14 I've noticed a few things.

1. When I try to dictate into Chrome using the standard entry or the Dictation Box my whole laptop freezes. I don't know whether this is since the Windows 10 1803 update as my laptop had already updated before I installed Dragon Professional. This is not a documented issue at the moment, that I could see from searching on Google.
2. I also had some problems dictating into a Blogger blog page using Microsoft Edge, whereby my laptop also froze. Using the Dictation Box delete didn't solve this until I changed it via the Dictation Box settings, to emulate typing text rather than a paste option; the only problem with the Dictation Box was that it did miss the first four or five words that have been dictated into the box but didn't make it onto the page when I instructed the program to transfer the text.
3. The programme Open Live Write enables me to dictate  straight into a Blogger template without the laptop freezing in Windows 10.
4. I started to use an old microphone headset from 2011, seven years ago, that worked well when I first tried it but then refused to work in any of the USB sockets on my laptop. I bought Jabra wired headset that is fairly new and I haven't had any problems since, in fact the boom microphone works a lot better than the shortened one on the old headset. I believe it is false economy to use an old headset with such a modern programme, having to correct things because of the microphone erodes the efficiency of the more modern dictation program.
5. I'm amazed at the accuracy of this dictation program given that I only practised on two paragraphs to set up the microphone and, as long as my diction is clear, I have had virtually no need to correct anything. The majority of things I have altered have been the result of either not thinking about capitalisation before I say a word or the desire to change what I have said once the words have left my mouth.
6. I did install the Dragon extension into Chrome, version 66 point zero point 5 something, but it does not seem to be functioning as I have not been able to carry out verbal commands in Chrome, even though the extension is turned on.
