I don't use the eraser but just tried it and yes, I get the same.
thin red line where ever the mouse goes, without a button being pressed.

also set the size to 100 and it does not erase, it just puts a thick red line across the item it should delete.

Thanks  - I see that now

Functionality still is lacking for me though

1. eraser leaves a thin red trail where ever it goes - even with no
button pressed
2. in vector mode it sometimes works - I have to draw a little red
line right in the middle of the path I want to erase, or across it -
'touching' has no effect
3. in raster mode it leaves a big (depending on width setting) red
blob on the 'erased' area

Anyone else having problems with this in OS X (or other OS)
