That is only a patch, it doesn't work at all for systems/businesses who are IE-only. Other software (ie: photopost) that will use the ubb cookie logs in without issues, so it's an issue that needs to be fixed with ubb.
I totally agree 100%
Almost all of my members are employees of municipalities and they are stuck with IE. Some work some don't and the ones that don't have no option to change browsers or add some plugin due to the desktop is locked down from the IT dept.
