[Lazarus] .lrs files

[Antonio Fortuny]

Hi folks.

Got a problem: I have a data module in a project with some TMemDataset
All of them have some fields in the FieldDefs list
Now I'm changing some of the datasets but new fields appear as not 
existing when they are referenced somewhere else in the project.
Finally I've seen that the datamodule.lrs file has not been updated 
since last year despite the changes I've done ! And of course the new 
columns are not in the datamodule.lrs file and when the new fields are 
referenced, program crashes

How to force the saving of the .lrs file ?
BTW, it happens some times with TForms

Antonio.
