Seems to happen only on that machine, as I can not reproduce it on other machines with the same setup.

I checked again and either I did not see it the last time or something change.

JOSM does not stall but all new windows open in the background and will not raise even when cycling through them. Only solution is to close these windows (using "WIN-key" window overview).
