Hi Folks,
 
 I've noticed a strange problems using my picasso II board with various
applications. Here's my setup
  
   A3000 030/882 25MHz (2chip/8 fast)
   Picasso II w/2 meg of ram
   DKB3128 w/16 meg of ram
   MultiFaceIII
   'couple of drives including CDROM and Zip.
 
 Anyway, so I was using AWEB on it's own public screen (a picasso 256 color
 screen, probably 640x480) and I use a 4 color interlaced NTSC workbench.
 Sometimes when I use AWeb like this and I try to switch back to my WB all
 I get is a blank screen. I can control-M back to the aweb screen and every-
 thing still works fine, but I can't get to my workbench without rebooting.
 This kinda sucks... actually, I can't get back to any non picasso screen.
 I do, however, hear that audible click the picasso gives off when it's 
 making the switch from it's signal to the pass-thru. What I'm thinking is that
 the picasso switches off the amiga's normal display hardware (?) and for
 some reason is forgetting to switch it back on when I go to an NTSC screen.
 Is there a setting for this somewhere? Could it be a hardware problem? I
 recently replaced my U202 chip b/c of graphics dandruf on NTSC screens. It
 has yet to show me more dandruf (except for my paranoid dandruf sightings few
 and far between). Anyway, any and all help would be appreciated. I've even
 tried the picasso switch commodity with no success. 
 
   Thanks much, and thanks for reading my ill compose paragraph.

I've had almost the same problem. The DBLntsc display would roll and shrink
then go away. Rebooting would bring DBLntsc back. No obvious time to failure.
