Open in from other app with passcode enabled, can not input in lock screen

Hello, I tried to reproduce it in the latest iPad and iPhone versions of Textastic (v 4.2.2) on iOS 6. It worked for me on both devices. Can you give me more details?

For example, PDF, doc, zip, tar.gz

Ipad2, ios6.0.1, the up to date textastic version.

Ah, ok, I see. It only happens with binary files, not with regular text or source code files.

I'll fix it in an update.

Only happens for binary files. Will be fixed in an update.
