Thanks for the quick reply.
Sometimes just a reboot will clear away buffer errors, however, I am unsure when it comes to cache. Since the caches (not seen via any MacOSX utility of which I am aware) all appear to be application-based, and if that's the problem-area, anything from a user logoff or a reboot may not be automated unless by another maintenance application.
To force a cleaning of some cache, I used MacTuneUp 3.6.0, which is not specific about which non-Apple application caches it clears, and I dio not know if it even does clear anything besides Apple caches, nonetheless, I am using it:
MacTuneUp --> Maintenance --> Clean Up --> Clean Application Caches:
[x] All standard caches
[ ] Mail
[ ] Address Book
[ ] iPhoto
[ ] iChat
[ ] iCal
[ ] Java
I performed this, and it still cannot be invoked, so any DW-specific ability to clear cache is unreachable to me from what I currently know.
Is this the cache you meant?
Other caches or clearing methods?
If this clears cache as the culprit, then perhaps there is some sort of integration bug w/r/t 1+ of the extensions and DW, an extension load bug (which the traceback might reveal), or merely a DW Preferences conflict resulting from a corrupted installation process?
I await further suggestions or already written-up procedures for resolution.
Remember, I do have the traceback from both systems, which will reveal exactly what crashed and in which order.... Would removal of all fix the problem? If so, I could install one extension at a time to see which breaks it?
