Out of memory error - memory leak problem

Hi,

I'm using MatCAD 15 and have plenty of RAM. For deconvolution I use a program freely avaiable in the Internet, which runs smoothly on my computer, but after a relatively short time (3-5 min) the program stops working and gives an 'out of memory' error, probably due to an memory leak problem. Can sombody give me some tips avoiding this problem?

best Jakob
