When I use my TWAIN scanner from within Photoshop, it launches a non-modal dialog (or frame, I'm not sure) with the scan options.

I just minimized this window because it was in the way, but I cannot restore (unminimize) it. It doesn't have a task bar button or a system tray icon, and it doesn't show up in Alt+Tab.

I know it's not closed because when I go to the TWAIN menu option in photoshop, it's still grayed-out. I've made several adjustments in the scanner dialog that I don't know out of my head and I don't want to lose either.

I've also tried the un-minimize shortcut Win+Shift+M, but that only seems to work after a Win+D or Win+M command.

  • And then I found it the solution. I found a little Windows 3.11-style minimized window in the lower left of the screen just above the start button, when I have photoshop on top. Jun 24, 2012 at 9:48

I'm not sure if it will help in your particular situation, but sometimes I find Far Manager useful as it can show list of processes with corresponding main windows with Ctrl+W and one can activate selected window by hitting Enter.

If you don't feel like installing Far Manager, I believe other applications that show more windows than Task Manager will do the trick. Probably Spy++ will work if you happen to have it installed.

  • +1 but how will Spy++ work if you cant drag the target onto a invisble window? @Zom-B By show more windows than Task Manager you can see programs like ProcessMonitor. Jun 24, 2012 at 7:18
  • @JeremyThompson Indeed I completely forgot about Sysinternals. It was quite a while since I ever used Spy++. I remember there used to be a comprehensive list of all windows (including children). I believe there is a way to search for the proper one. As I said I use Far Manager and List of Processes (Ctrl+w). It may help or may not in this case, but it does show some stuff that I can't access otherwise. The benefit of Far is that it is a good file manager as well ;-)

  • woops I meant Process Explorer not ProcessMonitor. Jun 24, 2012 at 7:40
  • I used Process Explorer, and sadly the TWAIN window doesn't show up as a process. It is simply a thread in Photoshop. And again, I'm positive the TWAIN window isn't closed, as when I thought I had given up and I wanted to close photoshop, it complained that a TWAIN acquire session is still running.

  • Furthermore, launching a second photoshop and trying to access TWAIN gives me an error that it is unavailable at the moment. Jun 24, 2012 at 9:38
