Product and version: FileMaker 16 & 17
OS and version: Windows 10
Description: In FileMaker 17 and 16 the function Get( WindowLeft ) returns a value that is 8 points to low, leading to a value of -8 when the window is maximized. Accordingly Get(WindowWidth) for a maximized window returns a value that is 16 points higher than the actual screen resolution.
The same applies to Get(WindowTop). We have also seen the value -7, this difference could be connected to global scaling settings above 100% in the Windows OS.
How to replicate: See above
Hardware: We see this behaviour on three PCs with different hardware (Dell desktop/HP notebook) and different graphic cards (AMD FirePro W2100, AMD Radeon HD 8750M, Intel onboard graphics)
