When I execute a "Replace in files" with the "Prompt on replace" checked, phped opens all files it searches, no matter if the string I'm replacing is found in the file or not. It's supposed to open only the files where the searched string is found.

If I search&replace a "no-exists-string" with "prompt on replace" checked in my project root, with the file mask set to "*.*" and recursively, phped opens *all* the files of the project except those it recognizes as picture (jpg, gif, etc).

If you have a pdf file in the project tree, phped will freeze. If it can't read such type of file, it should ignore it as it does with images files.

Thanks for your report.
This problem was confirmed by QA dept and is fixed by now. See build 4057.
