Normally, like tonight, I can alt tab between the two and firefox without issue. However last night, Vidyne's window wanted to be always on top of the others. I could alt tab to firefox or Tanchen, however even those windows were active(typing to group appeared to come from tanchen), vidyne's window was all I saw. I could get to tanchen's by moving Vidyne's window or by going to the desktop(windows 7 has the desktop as one of the alt tab options). However that night when I went back to Vid's screen, it always started this behaviour again.... so it was ruined for the whole night. It is not a huge problem unless I need to mezz, but when I need to mezz....... speed is helpful.
