1. yes i understand for thumbnail offset with windowblinds, i just put it as a observation. (full screen thumbnail previews display normally)
2. Well good news, in Windows 7 the transparency issue with Windowblinds is resolved. Even if you set DP to opaque and WB to transparent it's transparent.
3. Yes window=task.The thumbnails just get shown on both taskbars even when 'only relevant' is set in the DP taskbar settings.
4/5 The alphabetical order button got me confused, as one needs to set random change in the dropdown.
Thats why i noticed a difference in the image switching
For the rest no issues on both OS's
So it is a WB issue.....
