Xrystal, sorry but I forgot to mention that you need to press "Escape" to return to the normal cursor in which you can Drag/Select other widgets. I'm so used to AutoCAD that this is second nature to me. If there is anyway that you think might be better to accommodate this task, please share.
And as for Silverlight not working with Linux, I agree. I dream of the day when there will be such a powerful tool that is compatible across all platforms. There is however an open source implementation of Silverlight for Linux known as
Moonlight which is used to run Silverlight applications on Linux. Perhaps you could try this.
