    Re: Out Of Memory error when executing a function

    Yes, that is what I thought, but at crash time memory consumption is around 100-150MB. And even after weeks it stays in that range which I think would rule that out.

    Hello,

    do you use LoadPicture() in those programs?

    That is good news that you are able to compile on 11 and run on 10, that gives me hope it is just my setup.
