I've got the same problem in the past especially with PageControls
using until 10 pages and each page using 20 or 30 controls.

I started using forms for each page which are dynamically created and
freed as user navigates on page control, this way the resources are
freed.

About the exe size I abandoned exe compress schemes, build with
run-time packages scheme (which consumes even more memory because all
the package has to be loaded into the memory, instead of only the unit
code needed on link time) and replaced this methods for the Citadel
process of compressing only the resources which are dynamically
uncompressed to memory as needed. This way I also protect the resources
from being hacked.
