[Biococoa-dev] strider and gck format

[Koen van der Drift]

Hi,

One thing that the BCSequenceView will also need (or actually maybe  
its controller) is a method that checks whether what the user types  
is part of the symbolset of the sequence. If the controller does  
that, it's probably needed in a delegate method, such as

- (BOOL)textView:(NSTextView *)aTextView
		shouldChangeTextInRange:(NSRange)affectedCharRange
		replacementString:(NSString *)replacementString


And also a way to change every typed letter to uppercase/lowercase  
automagically.

Alex, I will look into the bug - that is indeed very weird, and  
difficult to debug :(  However, the fact that it only is for the  
first 10 characters, which is hardecoded in the default value of 90  
for the columnwidth, could give a clue.

cheers,

- Koen.
