RE: MI-L Save Window Memory Leak

How about considering this solution, even though it's just another way of
doing what you are actually doing right now:


Build 2 MapBasic applications, 1 that should be the main module supposed to
control the other.

1. Launch MB1
2. MB1 executes another instance of MapInfo with MB2 (use e.g. ShellExecute
for this)
3. MB1 sends commands to MB2, so that MB2 knows what job to perform. This
could also be implemented without
Exactly sending the command. MB1 could create a file with the commands. This
file is read by MB2 on startup.

But either way you, it's still a bit cluncky...
