Save As window don't block background window from actions

When you hit Ctrl+Shift+S (Save As) you think that your background become disabled for actions…
BUT it is not!
If you misc-lick on it, and start to typing name of your save file you can get explosion for background selected elements =)

I thought if this window can’t be minimized then it main window before it closed, like in other software or even in browser when you saving pictures.

So it must to be main window until hiting “Cancel” or “Save As” on it.

And I just found a bug with that window
when hit ctrl+z, area for typing text - disappears

I should probably bug report it…
