Suggestion :

1- Be SURE than no DA is currently running under "DA Handler".
2- Change (with ResEdit for example, but not with a DA) the TYPE of 
   "DA Handler" (in your System Folder) from "dahd" to "APPL".
3- Under the Finder, select "DA Handler" and GetInfo (Command-I).
4- Then change the size allowed to the "DA Handler" as if it is an ordinary
   application. Increase it of 50K for example.
5- Change back the type of "DA Handler" from "APPL" to it's previous "dahd".
6- Ta-Da ! It _SHOULD_ work.

No guarantees. Be really careful that when you are changing the type of
"DA Handler" (and when it's type is APPL), it is not currently running ! Bad 
case : you use DiskTop to change the type, but DiskTop is a DA !! Otherwise, 
you will have a lot of trouble in RESTARTING your Macintosh ("DA Handler" 
doesn't want to die -- it's human).

Hope it is clear enough to help.
