[TxMt] Finder window does not update after save

[David Wiser]

Using TextMate 1.5.7 under Tiger (10.4.11).  I have a Finder window  
open and sorted by modified date/time.  If I save a file in TextMate,  
the Finder window does not automatically update - I have to click on  
the file once and then the window re-sorts.  This does not occur if I  
save the same file using TextEdit, for example.  I do not use Atomic  
saves.

Is this a known issue under Tiger?  Does Leopard solve this problem?   
Why would TextMate behave differently than TextEdit in this case?
