There have been reports about incompatibilities between Uli's Moose and some versions of the following applications:
Now Startup Manager
PPP Menu
If you are using any of these extensions, you might want to make sure you have the newest releases and you should be prepared for crashes when the moose pops up during work. A good idea would be to wait some time after startup to see whether the moose will crash when popping up for its first pause phrase (not the "welcome" speech). If you depend on these programs working you will have to remove the Moose again (sniff!).
Accidentally I found out that installing Federico Filipponi's "MyEyes" extension seems to make PPP Menu a bit more stable.
Although I am working on making the Moose even more compatible, I can't endanger the Moose's stability by adding workaround code for the problems caused by the above applications (Besides, I have no idea what such a workaround might be).
