If I enter some text that begins with a space and select the entire line, pressing the 'convert to uppercase' button almost works. The text is in asctual fact converted to uppercase, but the space character at the start of the line is translated to  
For example, if I start with:
[ hello] (ignore the square brackets, the text I type in is contained within them)
pressing the convert button gives me
[ HELLO]
Thanks,
