Rocket Icon jumps to task bar when launched

Sorry for this stupid question!! I have done something when working with UE4 that now causes the program when launched to immediately minimizes to the task bar as the rocket icon. There appears to be nothing I can do to have it appear back in the window as a program. This is really dumb I know but for the life of me I can not get it to maximize back into the main window. Rebooting doesn’t help. It just launches and jumps to the bottom of the task bar as its icon. Using build #1711197 Any ideas??
Thanks so much

This has happened to me too… Twice I guess… When I minimized rocket once and it never got back again. I had to close it from Task Manager → Processes and relaunch it again… But then I was running many memory heavy programs and I assumed that was the reason.

I found the answer. It is Windows!!! Some how I closed the program off screen. I used the Alt-Spacebar to allow me to size and move the Rocket window back onto screen. Crazy–Sorry about the post.
