Inter-projects navigation

hi,
i found that it’s not possible to open a window from another project with standard nav options.
i am currently developing a demo complex project, made up by a father proj and and 2 sub-proj (this is important 'cause the sub projects are similar, so i’ll need to add more later).
is there a way to open another projects by script for example?
thanx

I believe this is the function you are looking for:
system.util.retarget(projectName [, gatewayAddress] [, params] [, startupWindows])

exactly!
thank you so much…

ok now my question is: is it possible to hide the blue splash screen showing loading status on changing project?

No you can’t sorry.
