Crash when double clicking first word in a text file

I am experiencing the same crash whenever I try to double click on the first word in a text file to copy and paste.  If I drag to manually select the word it works fine, but as soon as I double click to select the whole word, it crashes.  It happens on both my desktop and laptop, and only seems to be the first word in a text file.  Hope you are able to fix it - Textastic is a really great app!

Thanks,

Iain
