I have the same problems/bugs as before, sluggish opening of windows,
except that the save window position is fixed in this version. (Nice, thank you for that!)
Now Pale Moon x64 freeze when playing Farmville2 at Zynga/Facebook in fullscreen mode.
In fullscreen mode pale moon/flash player freeze up. Must terminate pale moon/flash.
When disable Windowblinds it all works fine as usual. So it's not about any partical skin.
As usual i uninstalled former WB version, rebooted and installed new beta.
I'm back at v 1.07 for the hundred time now or so since all versions after 1.07 have problems on my PC.
