Bug in "Replace in File" in 5.6?

[kinook]

It is a bug introduced in 5.6. We plan to get a fix out next week. For now, you can work around it by adding the following line to the step's vbld_StepStarting script event:

vbld_MakeFileWriteable(Step.ExpProperty(Builder, "FileIn"))

Create the script event (if it doesn't exist) by opening the step properties dialog, clicking Script Editor, switching to the Step tab, clicking the Events button, and choosing vbld_StepStarting().
