Windows 8.1 x64
I just now updated my ST3 beta to the latest version. I was confused at first because after I clicked “Update” from the “new version available” window, that window disappeared and that was it. I noticed on the taskbar there were two stacked icons for ST so I hovered over and saw the progress bar moving along…so I thought maybe it was some newfangled hidden thing. When it was done I could see in the hover that there was a button to click but couldn’t find the window anywhere, and clicking on it didn’t bring it to the foreground.
I ended up moving the window using my sneakymethod for when my second monitor craps the bed and that worked, which means the window was normal, just positioned off the screen. To do this, hover over the preview, right-click, select Move, and hit a keyboard arrow to focus on the window, then you can move the mouse to reposition.
It turns out the window was negative; that is, beyond the upper-left corner of my desktop.
Cheers,
