On Windows 10 Home 64.bit:
1 Install portable mode using defaults and exit.
2 Launch MediaMonkey.exe.
3 In tree, click Music, Drag a track to the player and in Now Playing click on it:
4 In Tools > Options > Skin, checkmark "Override skin theme with Windows System Theme (requires restart)" and se Font Size to 150% (

5 Click OK.
Expected: Font Size 150% on all text.
Observed: Font Size 150% on some items, but unchanged on tab ("Music"), Search box ("Music"), Tree ("No Playing" etc.), Column Browser headers ("Genre" etc.), Selected window content ("Title:" etc.), and player "MediaMonkey Player"):
Likewise if instead, launch is "MediaMonkey (non-skinned).exe" and "Override skin theme with Windows System Theme (requires restart)" is left uncheckmarked.
