i suspect that when resizing it keeps allocating new strings each time you resize, it is very likely that there is no memory issue since windows does not really guarantee your memory to be seen as freed once you call free on it, what it probably do is say "im just gonna tell you its been freed but i will keep it cached so when you want it you dont have to wait for long" as an optimization. memcheck will determine if there is a leak or not.

I noticed a similar issue on Linux. Oddly enough, when I run a memory profiler it doesn't show that memory is increasing when using the application.
