Comment 2 for bug 1386862

This error occurs also in Windows , Windows 8.1)

Everything is ok while the coordinate do not change:
Region: exists: waiting 3.0 secs for P(images/Windows/TomSawyerPerspectives/CommonImageMapPreview/ToolBar/WebCommonToolBar.png) S: 0.8 to appear in S(1)[-1360,0 1360x768]
Region: find: waiting 3.0 secs for images\Windows\TomSawyerPerspectives\CommonCanvasPreview\ToolBar\CircularLayoutCanvas.png to appear in S(1)[-1360,0 1360x768]
Region: exists: waiting 3.0 secs for P(images/Windows/SocialNetworkAnalysis/HtmlCanvas/SecondaryScreen/CircularExpected.png) S: 0.8 to appear in S(1)[-1360,0 1360x768]
Region: find: waiting 3.0 secs for images\Windows\TomSawyerPerspectives\CommonCanvasPreview\ToolBar\HierarchicalLayoutCanvas.png to appear in S(1)[0,0 1360x768]--- coordinate changed*******

All my tests are only one screen.
The question is why is different the coordinate after some tests? from -1360,0 to 0,0
Do I have to get the first coordinate and then set it for each test? (I'm using JUnit)

Regards!
