In a fresh *VC-log* buffer, as soon as I type "SPC RET", the cursor disappears and I get no response. Typing C-g restores control, though sometimes I have to C-g twice or more. It appears to be a display problem, as the display updates to reflect keystrokes typed before the C-g -- and sometimes the first C-g will update the display partway, and the next will update it more. Burying or killing the *VC-log* buffer makes the problem go away. Same with deleting the initial SPC character, which appears to be necessary. I have had no luck tracking this down any further. Setting debug-on-quit not only does not enter the debugger, it sometimes seems to cause emacs to hang indefinitely. I assume the next step would be to start emacs under gdb, but I am not familiar enough with redisplay (or gdb for that matter) to know what to look for. Any help would be appreciated. -- Bob Rogers http://www.rgrjr.com/
