Without doing something special a DLL does have it's own memory manager

So you can't (carelessly) pass FPC constructs lice objects or strings to
a DLL, because the memory management might fail. There are ways (at
least with Delphi) to make a DLL attach to a main programs memory
management.
A Form uses the LCL "Application" and thus the "main Thread". Creating a
second Main Form (-Thread) is not supported by the LCL.
So using the LCL, is it possible to e.g. put the code associated with a
right-button menu in a DLL, and have it interact with e.g. a SynEdit on
the main form?
