I have a similar but different crash to that decribed by joiwind with v1.523 and now v1.53. Version 1.0 did not have this problem. In my case with CD open every time I click on Dock Settings in the context menu and exit (not when it opens) CD crashes and I get a sequence of three error messages (which I too can't make head or tail of), one after the other on clicking Abort or Retry and I kill the process.
I am running CD on Windows 7 64-bit, am not getting any mis-behaviour on anything else, and otherwise CD works brilliantly (with just a couple of minor niggles that I will write about separately).
Any help or advice will be greatly appreciated.
