Since upgrading to 1.5 I've noticed that my Dock icons expand/contract in a very jerky way, in fact momentarily freezing when the mouse is over one Icon only to suddenly unfreeze a moment or two later when it's over another Icon. (I have them set to Autohide.) Changing performance options didn't seem to make any difference, and restarting the computer with a very basic startup (with msconfig - no non-Microsoft services, no startup items) didn't make any difference either, so it doesn't seem to be a conflict with some other program running on my computer.
Changing the system priority of ObjectDock to realtime helped a little bit, there is still jerkyness, but at least the Dock is usable. Of course, I could set the expand/contract when mousing over the Dock to be off, but I would like this program to behave as designed. Anyone know what could be wrong, or have similar issues?
