I can't really submit a bug report because the issues themselves are unpredictable. I'm assuming that it's related to the Wacom tablet because people using mice at work don't seem to have the same issues:
> - When sculpting, sometimes the tool continues to modify the mesh even after the pen has left the tablet. (Repeatedly clicking off the model or tabbing in and out of Blender solves the issue.)
> - When UserPreferencesEdit.drag_immediately is true it works as expected, but every so often the behavior defaults to how it works when UserPreferencesEdit.drag_immediately is false. Toggling the value in the preferences window has no effect; restarting Blender fixes the issue.
> - The corner drag handle that's used to split areas is extremely hard to click on. (With a mouse it's much less so.)
> - There's a noticeable (50 - 100ms or so, by my estimate) lag between when you put the pen to the tablet to rotate the 3D viewport and when the viewport actually begins rotating, moving, or trucking. This lag is considerably lessened by going into full screen mode, but it's still apparent enough to cause a jump when positioning the view.
> I think the problems have something to do with a threshold value; past a certain pressure threshold the system registers a click, but sometimes that threshold is not passed yet the system driver sends a click message, which confuses Blender. Is there a way to debug tablet values directly inside Blender by, for example, reading RNA and having it pump into text fields created by Python? Perhaps some way to piggyback on system messages for input without eating those messages?

Why system are you on and what pad are you using? What version of 2.5?
I know that 2.5 gets really crazy on my system when I run 2 copies at
the same time and then it gets very buggy and slow. I have also not
reported this because I don't know what to report.
