photoshop elements editor window loads offscreen

[poppanona]

My window suddenly started loading  offscreen such that the tools sidebar is hidden. I can't move the window back with the mouse.

However, I can perform functions from the menus. I haven't a clue why this happened or how to correct it.

I am on a Mac desktop with OS Mojave

Thanks

Can you drag bottom right? Hover your mouse until you see double arrows and drag up. Then try to re-size the window to fit your monitor.

Adobe support solved my problem before I saw you post. I didn't click on the correct part of the screen to move it. When I clicked on the black portion above the  menus, I could move the screen back to where it should be.

Thanks for your suggestion
