Space and Back does not work unless fulscreen

[Sprintdriver]

Applies to version 4.23/winxps p2.

Problem is that only happens some few times. Now for example when I was browsing, rotating and saving some scanned big bmp-files.

Closing down IV and starting with next picture.

Reproducing error
* Open one (of several) big BMP file that is bigger than screen when zoom = 1:1
* Using the image straighten tool, little angle about 1 deg or so.
* Crop the image.
* Save image (using Ctrl+S). Answer Yes to overwrite. All three optionss is ON.
* Now, the Space and Back buttons seems to be disabled when zoom=1:1. I can still use them in fullscreen. When I goes back from fullscreen, they don't work.

I think somehow the Paint toolbar is interfering with the keyboard in window mode.

Some users probably appreciate this quirk, as indicated in this thread.

This is by design. Close the Paint Toolbar to resume browsing.

You can still browse using the IrfanView toolbar buttons and menu entries, even if Paint is open.

Ok, I didn't know that the Pain dialog prevented Space and backspace.

Anyway, it also applies when main window has focus and paint window not focus. But no problem - I can always hit F12, and it sort of solves the issue
