[Mac OS X Lion] Impossible to save sketch

[GoogleCodeExporter]

• What steps will reproduce the problem?

1. Launch Arduino IDE
2. Load an existing sketch
3. Edit that sketch 
4. Save the sketch

The sketch is not saved because the existing file is write-protected.
This is part of the version-management introduced by Mac OS X Lion. 

• What is the expected output? What do you see instead?

Sketch saved

• What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

Arduino IDE 0022 on Mac 10.7.1
Arduino UNO

• Please provide any additional information below.

Manual solution is to edit the permission of the sketch file.

Two options: Arduino IDE next release could either include Lion's 
version-management or get rid of the protection scheme.

Did you already try and fix permissions in disk utility? 
Did the Arduino team already fix this?
I'm using Arduino IDE 1.0.1 on Lion 10.7.4 and it works.

I've never seen this happen, so I'm closing as invalid.  Please re-open (or 
open a new issue) if you can confirm.

I'm guessing this might have been an example, which are treated as read-only so 
you don't modify the included examples but instead save new copies.
