Possible memory leak in Series 60 Theme Studio

[rootshell]

I downloaded the Series 60 theme Studio for Symbian OS today and I found that it was using an aweful lot of memory on my system. The point at which it crashed Windows Task Manager reported javaw.exe (the process to which Theme Studio is attatched) was using 640mb of RAM. At the moment it's using 345mb, which is still a lot for something that is only dealing with small images. Is this caused by a memory leak and has anyone else had the same issue?

An update: I can't perform large tasks with the theme studio (such as generating the SIS file) as it crashes the program. Taskmanager doesn't show it as not respoding, however it just locks up.

All Nokia Theme Studio's have that problem. They are obviously coded badly.

I felt the Series40 ones are a bit worse. However, even though the desktop performance is unbelievably bad, those tools still function and are free.
