Since updating from Fusion 1.1.3 to 2 I had a lot of issues.
One of these are that keyboard input is slower and drop key presses.
I have noted this when pressing doing combination key presses like cmdv / cmdc.
When I'm typing at my normal pace Fusion often miss the cmd key.
The result is that a basic copy and paste operation sometimes ends in replacing a selected text with a v and sometimes what you thought was on the clipboard is not there.
The cut and paste between MacOS and Windows and within windows was a one of the things I enjoyed in Fusion 1.1.3.
It made integration between MacOS and Windows appear seamless and nonintrusive.
Now this is no longer the case and I find myself typing slower, handling Fusion as a rotten egg to avoid dropping characters when typing.

This issue is no longer an issue as I am now running Parallels 4.0
