[Inkscape-user] Idiosyncratic mouse behavior in Windows!

I've just installed Inkscape on a Windows XP machine and am having major problems with the mouse. I've tried both the latest distro and the stable one with no difference in behavior.

On clicking the mouse pointer on the Inkscape window, the action takes place far to the right of the window, not under the pointer. Not only does this make creating objects difficult, it make selecting them impossible!

BTW, I've not found how to make the grid finer than the default 5mm one. Can it be done (like in Xfig)?
