I have this document open in another app, and in certain occasions, the document within TextMate/TextWrangler would revert itself to the previously saved versions whenever I hit Cmd+S. This is very annoying as my changes are basically gone.
I'm pretty sure both TextMate and TextWrangler are not sandboxed. The version of TextWrangler I have is the one from the Mac App Store.
Anyone has any workarounds for this?
