Hi Serge!
Here never used Ambient, only Opus Magellan for months!!
If you want to use it as your desktop manager instead of Ambient remember to copy in libs: the old icon.library from WB3.9 and to deactivate in Magellan settings -> Miscellaneous the gadget "Mouse buttons over inactive banks".
Naturally forget png icons in Magellan desktop!
Ah, a last suggestion: setenv envarc:dopus/workbenchtitle 1

Enjoy the best "OS" of al the times!

P.S.Hey Gerber when listers will be finally ready in Ambient? As you can see I'm not the only one that needs them..
