We have fixed many bugs (found in WINDOW 7.7.10) in WINDOW 7.8. The latest version of 7.8 is 7.8.24.
That version is not yet on our public website, because we are still fixing more bugs (!), but if anyone wants to test it out, here is a page that has the latest installation files for the 7.8 versions of both WINDOW and THERM.
There is a list of the fixes for each program on that page, and if you do test, and find other issues, please let me know, since we are actively trying to fix as many issues as we can right now.
Thanks for your help in making THERM more robust.
