I'm new here and I'm really glad to find a place that is so dedicated to old software/hardware.
Anyway, I've been using the excellent DOSidle utility by Marton Balog for a long time both in virtual machines and on real hardware. It works great with one notable exception: in most programs the mouse becomes nearly impossible when DOSidle is active - the mouser pointer jerks and the mouse clicks are ignored most of the time. This includes Borland C++ 3.1 IDE, PQ Magic 3.0, Norton Ghost and many others.
So, I've decided to fix this annoying problem and to create a 2.50 version of DOSidle. Please note that while the source code of DOSidle is included, unfortunately it was incomplete. I had to reverse engineer the missing portions of the code, which means that it is possible that there are some bugs that are not present in the original DOSidle 2.10. Also, please make sure that DOSidle is loaded after your mouse driver, because otherwise it won't be able to hook to INT 33h.
I'm posting the updated version here in hope that it will be useful for someone else too. Please let me know if you have any problems or found any bugs and will fix them (whenever I can find time, of course).
UPDATE Aug 12 2015: There is a new release DOSidle 2.51, which you can find here DOSidle new version 2.50 (fixes mouse problems).
