Thank you for your troubleshooting, it helped me out a great deal because there is infact a very easy and common solution for this problem...
right-click you artweaver-icon
a menu appears, choose the option "properties"
a window apears, just under its top border you can see a collection of tabs
click the tab that says "compatebility"
now check the first checkbox(from the top)
it enables compatibility-modus and the grey dropbox under it becomes active and lights up,
click the small arrow at the right-side of the dropbox and choose the option "Windows XP(service pack2)"
now you shoud also check the last checkbox (the most bottom one) to run artweaver as administrator.
launch artweaver and enjoy it as it was meant to be
this is a (semi-)permanent solution so it shoud never be repeated again, unless you choose to open artweaver whit another icon(modify the executeble in the root directory to avoid this) or after reinstalation
hope this is of any help or my registration here woud be a waste of time
