Huh, that is interesting! So you can fix it, and if I understand correctly in versions of DOSBox before a certain time the default settings had the issue not occur? Now I can imagine not having the issue as a kid, but I have gotten so used to it that I feel like I've always had it. :P But I guess it did indeed start occuring when I reinstalled DOSBox after getting a new pc. I have had such recall issues with games before! At some point I was positive I used a website between 2006 and 2011 that turned out to exist since 2013. I was very confused when I found that out, but the WayBack Machine from archive.org helped me fix my memories.
The site I used to use had a similar purpose, but a very different look than the new site, and yet before I saw the old site again I could remember, I thought, using the site with the 2013 lay-out all the way back in 2006!
And thanks for explaining the issue, as well. :)
