I don't think it is the size of the file. I think it is getting confused with some of the text. Especially when I tried with 2447 and a string of "[][][][][][][][][][][][][][][][][][][][][][][][][]" appeared at the bottom of the screen.
I tried it with RJText editor and that find/count finished in 1-second. -- <http://forum.pspad.com/read.php?6,59546,60026> PSPad freeware editor http://www.pspad.com
