Photoshop CS2 magnetic lasso last point deletion not working

[cow_2001]

Hi,
I've installed Photoshop CS2 using WINE. Everything, except for the magnetic lasso tool's last point deletion, works.

Using Ubuntu 8.10 Intrepid Ibex.
I've tried uninstalling all compiz packages but it didn't do any good.

Any solutions?

Thank you very much,
Yuval.
