Wen-Ming, I am no expert in Twc but I have observed the behavior you've described. It seems that when using the X button to delete the task, the program gets the name wrong. Note that the pop-up asking you to confirm that you want to delete the tiddler, it only gives the first word of the name.
My work-around would be to not use the X button but the click on the name of the task and then delete it directly. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
