Split will not work with Cut/Paste?

Ok i have a program that will split numbers based on the space in between the numbers, this works all fine if I type the numbers in the textbox, but if I cut/paste the numbers from say Notepad or Work the program will not work, now the numbers are in a column instead of rows of them, BUT it will work if I type them in also as a column? I've been playing with different regex's like \p{Punct} and \p{Space}, these work but not if I cut/paste the column but will work on a cut/paste if they are in row form?

I'm lost any help.
