My online updater uses sockets. I would need for it to be able to download new or updated dll's for the script without issue.

I have tried one more test to directly write to my documents folder, and that test succeeded.

Any writes that are to the mirc directory are redirected to their compatibility folder without issue.

While this is a windows issue, I'm sure a workaround for mirc can be made to fix this.

In the meantime, I will continue to work on my own workaround for this whether this is fixed or not.
