Tnx Don,
You w7 users are "lucky" as your not subject to the myriad of intrusive w10 updates, each making one cringe when re-booting.
Dennis,
Another LoTW upload today with the same un-closable window. Instead of just closing and re-launching LOGic I navigated to Tools/Setup/Misc Ham-setup like I was going to change something. When doing that LOGic closed all its open windows (including the frozen window) before displaying the Misc setup window, I hit "cancel" to that and LOGic re-opened as usual and the previously frozen LoTW Upload window remained closed. Not sure if this helps any.

UPDATE: I didnt think to look if the LoTW Upload window can be set to "Always Stay On Top", it can and mine was not. Setting it to Always Stay On Top I did another upload and it didnt freeze. Not sure if this is just a coincidence but try it. I'll report back if its "repeatable" at least for me.
