build on linux latest svn :
get a whole bunch of these entries in the log ....
KeyBinder failed UpdateById ...
What does it mean, and how to get rid of it ?
You mean the "debug" log don't you?
It means you have a very old cbKeybinder10.ini file in the CB data folder. The menu structure has problably changed many times since you last did a key save.
Either delete cbKeybinder10.ini or open the keybinder configuration dialog and choose OK. It'll resave the structure.
This happens to SVN versions that have added/deleted menu items and the menu id's nolonger match those in the .ini file.
This will not happen to a released version.
I have recently turned "dynamic merging" back on. So keybinder will eventually clean out all the stale menu id's. But it does it slowly.
