Hi Vince, the problem where the OK and Cancel buttons do not work properly when IE8 is installed is fixed in the 1.1 update.

You can download the update installer here:
http://moi3d.com/1.0/update/moi_v1_1_update.exe

If you run that updater, it will patch your 1.0 install to be version 1.1 that should now work properly with IE8.

Please let me know if you have any problems after doing the update.
