Another popup (2.1.2) question:
So far I couldn't get multiple popups opened with a folder at the first level with:

Only the last popup defined in the step.rc works on first level.
Is there a way to get this ?

I think you want to use !PopupDynamicFolder [somepath] as a regular bang.

e.g.
!PopupDynamicFolder "$CommonPrograms$|$Programs$"
or
!PopupDynamicFolder "$ThemeDir$"

Defining multipopups with custom entries is done like:
Traditionally "!howDoYouWantToNameIt" begins with "!Popup".
e.g. "!PopupWhatYouWantToNameIt"

What I am searching for is a possibility to open several popups with a folder at the first level i.e when the popup opens it should immediately display the folder content. This works fine with one folder (the last one defined at the end of the popup declarations in step.rc), but not with several popups. It would make a big improvement in terms of Fizzes'es law compliance.

try the first example tnl gave: instaed of defining a separate popup, call

by itself, not in a *popup line

Yes, thats it ! I didn't know popupdynamicfolder isn't a pseudobang. Easy. Thanks!
