This is a new one. I did "UPDATE /U". After pressing the "Install" button I got "Unhandled exception in TCMD.EXE (pid 2348) ... want to debug?". I don't think I got that before. I said "Yes" but nothing interesting came up in the debugger. When I looked, there were **two** TCMD.EXEs running (neither started by me; I haven't run TCMD in a week or two). When I dismissed the debug dialogs, I got a mbox with a a stack trace. At the top was 0x0048A123 (unnamed, in TCMD). Then UPDATER.EXE told me not everything installed properly. When it was all over, I **had** (apparently) upgraded to build 61 (all the important files were dated 4/10/2011.
