Crash with Preset and Pictslider or Filtergraph~

I recently upgraded to from Max 5 to 6.1 on Windows 7 and am baffled by a really simple problem: when I load a preset object together with a pictslider or filtergraph~, saving a preset immediately crashes Max.

Here's the Windows 'Problem signature:'

Is anyone else having this issue? What else can I do to understand what's going on exactly?
Thanks!
