No, I tried a couple more things. Created a new empty notepad, copied and pasted the contents of the original, tried ctrl f, crashed. Then I copied and pasted about half of the original. Then it worked fine. 3/4ths, worked fine. The limit seems to be somewhere around 30k characters or 5k words (I assume the search function would loop over characters but I could be wrong). After that point sk closes. I'm guessing some kind of overload? The solution seems to be splitting up my notepad, but now I'm more curious as to why it's doing this in the first place. EDIT: It doesn't matter whether I'm running RS or not, IRC or not, or everything at once. I believe the first time I had this happen was when I was boss hunting; fortunately nothing terrible happened. At that time I just chalked it up to some random glitch and assumed it wouldn't happen again.
