Mathcad Memory Leak - Large Data on Clipboard

OVERVIEW:

1) I copy a large table from RISA-3D

2) Open a blank Mathcad Sheet

3) Look in Windows Task Manager, The Memory for mathcad.exe *32 increases DRAMATICALLY when Mathcad has focus, when Mathcad doesn't have focus; Memory only increases by 500 KB per second.

4) this 'RAPID' Memory use can be terminated by copying something MUCH smaller (i.e. A string variable from mathcad itself)

5) After copying something smaller, mathcad sill has a large memory allocation; only way to free it is to terminate the Applicaton

6) If I fail to copy something else; mathcad runs out of memory preventing me from saving and eventually crashes.

SPEC:

Mathcad 15.0 (15.0.0.436 [006041742])    -> MC15 M020

Windows 7 Proffesional; Service Pack 1 (64-bit)

QUESTION:

Is there a fix?  OR am I just going to have to copy and past quickly?
