I tried opening the project in Delphi 7, waited 1 minute until i used taskmanager to shutdown hanged delphi... Checked mapedit folder to see the horrible truth: 36Mb big form file and 15Mb exe! Please make them load dynamically on startup :shock: Now that this part is known, i may suspect you are starting to run out of memory and program starts doing unsuspected things.

More so, tested exe that you compiled and didn't see problems:
