Javascript file locked when breakpoint added

I'm using Visual Studio 2003. In debug mode, whenever I add a break point in my javascript (js) file, the file then beco开发者_StackOverflow社区mes locked so that it can't be edited.

Closing the tab and reopening it seems to unlock it.

What I'd like to know is: why does this happen and is there some kind of setting that would prevent this from happening?

I think this is by design. When you hit a breakpoint Visual Studio shows a copy of the actual file. You cannot edit it during debugging.

Found this macro which automatically closes and reopens the js page you are on, and moves the cursor back to the line you are on. Hope it comes in useful to someone.
