[news.eclipse.platform] No Workspace Launcher w/o -clean

[longwell@xxxxxxxxxx (Scott Longwell)]

I am working on a product based on Eclipse 3.4 and am seeing some curious 
behavior: after starting the product, creating a workspace, and exiting 
the workbench, subsequent startups do not prompt for the workspace name 
unless I specify the -clean startup option.

Window->Preferences->General->Startup and Shutdown has "Prompt for workspace 
on startup" checked.

Looking in Help->About...->Configuration Details in the *** User 
Preferences section, I see that SHOW_WORKSPACE_SELECTION_DIALOG=true is in 
effect: 
/configuration/org.eclipse.ui.ide/SHOW_WORKSPACE_SELECTION_DIALOG=true

Digging through the org.eclipse.ui.ide.prefs file, I see 
SHOW_WORKSPACE_SELECTION_DIALOG=true

Does anyone know of any reason why I would only get the workspace 
selection dialog if I start eclipse with the -clean option?

BTW, I do get prompted again if I cancel out of the workspace selection 
dialog, but not if I proceed to bring up the workspace.

Also, I never see a splash screen with or w/o the -clean option.
