I am reporting a bug that has been present in the last few versions of gFTP. When a selection of files has been made for download and the download has begun, you cannot remove more than about 5-6 (sometimes trying to remove 1 is enough to lock it up) of those files from the download list without it crashing the program. Actually, lock up the program is more the correct term as the program has to be xkilled. There is no way to recover from this that I'm aware of. You must restart the program to recover.
Regards, Jason
