Memory Leak

I cant seem to locate the memory leak in my code.

Pardon my coding style, still trying to improve.

ignore line no. 82.

i think the memory leak occurs somewhere in [B]dates()[\B], [B]scrollbar()[\B] or [B]class Tiles[\B]. But i think most probably between line 85 - 100.

What i want to do is to destroy the tiles and reconstruct it without the program eating the memory everytime it destroys and reconstruct it.

thanks.
