I do not use XEmacs 21.5! But what i can say is: Using `set-window-configuration' in ECB is a somehow and probably very unused feature and should IMHO be removed because really unnecessary. But Kevin, another developer of ECB, wants this feature - at least he has wanted it some time ago - i will asked him if we can removed this stuff. Even we do not remove this call we can call it conditionally only if an ECB users really want using this feature - which will be disabled by default. Another remark: The error comes from an advice for `delete-window' which is needed by ECB to work correct! This advice has to be activated during ECB runtime but if this is a problem we could call `set-window-configuration' by a wrapper which temporally disables the ECB-advices - but i general this is not a really good idea and i would not do this if not really necessary. OK, maybe Mike can better answer why really-set-window-configuration tries to delete-windows and why this is necessary. Then we can decide how to fix the problem and also who is fixing it, Mike or i ;-)

Ciao Klaus [...]
