Jon -

Good summary. The questions about memory leaks came up in the question from Joe about why the DT locks up when he uses it for "a long time." Several of us have commented about the possiblility that accumulating trash on hard drives can cause - or at least contribute to the kind of problem described.

This is not a problem unique to Windows, but in other OP systems, it's usually clear that the problem is with a specific application. The fact that Windows, in all its various flavors, does try to give programs the resources they need may disguise the source of a "hang."

Good maintenance, especially keeping disks clean, is one key. Understanding a little of how Win programs work, - sometimes in spite of what Mickey tells you - can at least make the "glitches" easier to handle and thus more tolerable.
