[Scilab-users] Scilab 6 problem with "Prettify"

I think you're right. The clear statement (without specific reference to 
anything) seems to clear a bit too much, so I've removed it from the 
initialization part of my script. Not only does it clear too much, but I 
have to reboot the computer to get it to behave ... at least, this 
solved my problem once. As with my other messages tonight, things seems 
to be "messy" and I'm not comfortable speaking in general terms until I 
have re-tested this over some period of time.

P.S. Sorry for the _many_ emails today ...

Best regards,
Claus
