It has been mentionned before, but with SAB 3.6.3 to 3.6.5 installed, the window title bar text gets bigger in several applications (as discussed on elevenforum)
In SAB 3.6.3, 'Use new font' was not ticked, and changing 'Control Panel\Desktop\WindowMetrics' fixed the problem only temporarily.
After reverting back to SAB 3.6.2, the problem did not reappeared.
Any chance to fix this in a next version ?
