That seems to have done the trick. Many thanks.

Working on it ...

Packages? Sorry, don't understand. I built the program from source. Attach a debugger? Er, maybe. I'll look into it.

Again I am not familiar with the code base, but when I looked last night, it seemed to me that the colour is being used to build a tree. Surely there's more than one tree in the manager pane.

I see the colour asserts even if the symbol browser is disabled. I imagine CB hangs because of those asserts.

Sorry to appear impatient. I'm not. I've already tried disabling the symbols browser, but it has no effect.

There's always that. This is my first time here, so may I ask how long it might take for the changes to result in a new svn?

Not that I know very much about the codebase here, but surely the latter would be safer. More future-proof??? Many thanks to both of you for your time and effort BTW.
