Screen maximising and menu problems on Windows 8 tablet

Issue report by David Dennis

Product

FileMaker Pro

Version

12.0v4

Operating system version

Windows 8

Description of the issue

This problem was discovered when I added a Mac authored solution to a HP Elitepad 900.
Windows 8 has a setting in the Control Panel which boosts the size of screen objects and fonts, as a 1280x800 pixels on a 10" screen is tiny.
It is found under Control Panel -> Appearance and Personalisation -> Display

The heading "Change the size of all items" is set to "Medium - 125%" by default.

This means that Filemaker menus and layouts are all stretched (badly and pixelated) to 125% of their proper size. It also has the effect of making some menu items unresponsive. Especially items that are at the bottom of the menu.

Steps to reproduce the problem

Get a Windows 8 table PC and set the screen options to the default "Medium 125%".
Then open Filemaker Pro and maximize the screen - see the crappy look of it.

Expected result

Software should operate normally, but doesn't. This error even occurs when no database is open.

Actual result

Try and click "About" or "Preferences" in the menus and you can't. The menu just closes.

Exact text of any error message(s) that appear

No error message, just bad screen behaviour.

Workaround

Set the screen to "Small - 100%" setting and instead edit the sizes of just the system font settings for Title, Menus etc.
