Strange Error.

[theLizard]

I occasionally get the following error when trying to save a file.

Module 'form a' links to module 'form b' which cannot be found in the current project. Do you want to remove / redirect the links to another module? Y/N

If I answer Yes I get -- Access Violation

If I answer No I get -- Module 'form a' references another module and cannot be saved until 'form b' is loaded.

The other odd thing is that even though it says module cannot be saved, it actually is saved...

This does not happen all the time just some times, does any one or has any one come across this before?
