[cdt-dev] Reason for read-only storage?

["Schaber, Gerhard" <Gerhard.Schaber@xxxxxxxxxxxxx>]

Hi!

 

Can anyone tell me, what can cause a storage to be read only? The following error appears sometimes when I start the application with only closed projects, then open one project, and then save the language mappings in the corresponding property page. I can't tell what caused this problem. The error does not appear anymore for some reason. I just want to make sure that this does not happen again.
