If you can't find it that way, you can always reset Vegas back to it's "factory installed" state by holding down Ctrl & Shift while starting it. Be warned though this resents all settings properties changes you've made so you'll have to redo them. It shouldn't lose any templates you've created though.

The trick makes use of an ancient Windows 3.x (or maybe even Windows 2) feature that lets you use a keyboard function for anything a mouse can do. In your case you need to get to the Window Move function which everyone does nowadays by clicking and dragging on the window title bar.

But you can't see the title bar, so you can't click & drag it. Oh dear!

Well, here's the trick: In Vegas, activate the pan/crop window (even though you can.t see it) by clicking on the pan/crop icon on any video clip. Now use the keyboard combination Alt + Spacebar. What this does is open the control menu for the active window.

Because your active window is out of view you won't be able to see it, but not to worry - it's really there. Now push the M key to select the Move function. This gives you arrow-key control of the window.

Hold down the Up arrow key until the window comes into view. Then you can either continue to use the arrow keys to get the window in it's desired location, or you can go back to the standard method of clicking/dragging the title bar.

Note that I said to use the Up arrow key because you said you think you moved the window off the bottom of the screen. If it is off a different side then Up will not get it back for you. You have to use the arrow key that reverses the move you did (whatever it was) that got the window off the screen in the first place.

You might have already tried this . . .

Go to View on your toolbar and ensure the particular windows is checked. If it's unchecked, it won't show up no matter what you do.

Hope that helps.

Alt + V -> Y -> L (Case insensitive)

Done.

musicvid,
maybe it's my keyboard, but with Alt + V -> Y -> L, pressing L does nothing to me. Pressing Alt + V -> Y -> D ( or Alt + D) of course gives me the Default Layout, but I still have to move the taskbar to see the hiding window, if it's 'down under'. Closing and/or exiting doesn't change this. A setting I'm missing?

Thanks to everyone for the helpful suggestions. The one that worked best for me was yours, Birk Binnard - thanks to you, I've now got my window back in operation.

I tried your suggestion, Musicvid - Alt +V -->Y-->L since it sounded like a neat shortcut, but I couldn't get it to work. Alt +V brought up the toolbar menu, the addition of Y brought up the Layouts sub menu and the addition of L did nothing at all - perhaps I've interpreted it wrongly?

Judging by remarks elsewhere on the internet, this problem of a disappearing window sounds quite common - a pity Sony doesn't anticipate it and give instructions for a solution.

I think it's a core Windows bug in the first place. Windows shouldn't ever allow a window to be moved completely out of viewable range.
