How do I unlock the forms (for editing) in a vb6 project?

One form (the main one) is open, but the rest are locked and read only.

Thanks for help.

View -> Toolbars - > Form Editor

after doing this the Form Editor toolbar will come out, then click the LOCK icon there to unlock or lock a form.

When I open project explorer, the main form (top of list) is unlocked and editable.
All others below it are locked.
If I open one of these it shows "read only"
View->Toolbars->Form Editor shows a blue lock symbol.
click on blue lock symbol, it won't go away.
If I try to edit, I get "File is read only"
What am I missing?

Does this have anything to do with Visual Sourcesafe?

Thanks,

This happens if the project file is copied from a CD where all the files are read only. After copying the files to system from CD check to ensure that the files are not read only (uncheck the read only check box).
