If one opens a dialog/window containing a RadSignature-control and resizes the dialog (e.g. make it twice as large) then the position of the cursor on the canvas does not match the position of the strokes anymore. Painting in the top-left corner is sort of okay/close, but the further one moves the cursor towards the bottom-right, the bigger the offset will be.

The following JavaScript error is thrown when RadSignature is used along with asp:ScriptManager:

Sys.InvalidOperationException: '_uniqueId' is not a property or an existing field.
