Modpack open on taskbar, but not on screen.

[MaddyIsNotHere]

When I open a modpack, it opens on the taskbar but does not appear on screen. I can't bring it to the front, it just doesn't exist. My computer is fully updated and I have no idea what to do.

So far, attack of the b team  and blightfall do not work but hexxit does.

Does the icon disappear ever, and if not do you eventually hear the main menu audio playing? If the icon does disappear please provide us with the log file.

Otherwise try Shift+Right Clicking the icon, selecting "Move", press any arrow key and then see if moving the mouse around moves the window back into view. I've experienced a similar issue with Minecraft before where for some reason the window gets moved offscreen, and that's the only way I could get it back. It doesn't make sense for hexxit to work though and not the others, if this is the case.
