Hey Ivan, thanks for the info. I've sent a Bug Report too. Please folks, as Ivan said, DO NOT DOWNLOAD this filter for a while until you get some news from FF Team.
This filter is Frozing my FF version 1.007 and next time you try to open up FF it will keep frozing FF because FF keeps trying to open up this filter and you won't get to open FF. Just in case you use the Frozen Stalactites and it keeps crashing your FF, please find the files Library_1468-1.ffxml and Library_1468-2.ffxml and delete them or rename them to .old. These files used to be into the folder C:\Documents and Settings\UserName\Application Data\Filter Forge\System\Library and C:\Documents and Settings\UserName\Application Data\Filter Forge\System\Cache
This way you will get to open FF up again.
Cheers,
Lucato.
