Previously I was running 10.6.8 :).<div class=""><br class=""></div><div class="">So. If I pop up an new Xterm and start typing in many cases a few characters in the typing cursor will transition from solid block to rectangle. Naturally this means my input is lost. A few seconds later it will transition back again. At that point I can continue typing.</div><div class=""><br class=""></div><div class="">Sometimes when the keyboard focus departs I get a beach ball. Sometimes when it departs it never returns, but if I click in the terminal I can restore it.</div><div class=""><br class=""></div><div class="">I can occationally get this to happen without typing. I just open the xterm and start and the black keyboard cursor and after it bit it disappears, optionally I see the beachball, and optionally it comes back after a bit.</div><div class=""><br class=""></div><div class="">This behavior occurs dependably and repeatedly if I have work to do. I occurs less reliably if I’m trying to reproduce the behavior or record it in a screen capture. But even if I do record it it’s boring because all you see is the cursor changing.</div><div class=""><br class=""></div><div class="">Is anybody else suffering this affliction?
