Frame size issue in metaphone3 cluster and edit

I am using OpenRefine to clean text from a CSV file. I've been working on the same project for several weeks, and it was working fine until this week.
I am trying to use the 'Cluster and Edit' function from the 'Edit cells' menu. When I use the 'fingerprint' and 'ngram fingerprint' keying function, the frame that opens up inside the browser window is sized appropriately, and I have access to all the buttons and selection menus. However, when I try to use the 'metaphone3' keying function, the frame that opens up is way wider than the browser window, the sliding selection boxes that usually appear in the right side of the frame are not visible, and the buttons across the bottom of the frame ('Select All', 'Unselect All', etc.) are not available. I'd really like to be able to use this keying function option again. Does anyone know what's going on, or how I might be able to fix it.
I am using the OpenRefine 3.3 beta, although a similar issue was happening earlier this week with all keying function options in 3.2 (all were working fine in 3.2 as recently as Friday, 10/25/2019). I am using Firefox, although the same issue happens in Internet Explorer. The system OS is Windows 10 Enterprise.
Thanks in advance!

Access 2016 sizable form borders too narrow under Windows 10

I don't know if this is a general problem with Office 2016, or if it is specific to Windows 10 users, but I find that sizable MDI forms in Access 2016 have a single-pixel border that is very hard to grab with the mouse.
The form borders show as a single-pixel red line, and have no difference in appearance regardless of the mode of the form, whether the mode is "no border", "dialog", "sizable" or "thin". The border appears the same in design mode, as in the example below.
I've tried this on a couple of different computers running Office 2016 under Windows 10, and the problem is the same, so it's not a driver issue. I've opened the database under Office 2010 and Windows 7 and the borders come up at the normal size for Windows 7. I haven't tried Office 2016 under Windows 7 though.
I have to assume that the problem is related to the way that form borders are handled in Windows 10, where the drop-shadow forms part of the draggable area.
Is there any way around this?
Yes and it's a P.I.T.A. The 2 workarounds I've been using are,
1. 'slide' the mouse along the border you want while vigilantly watching for the curser to change and then go mouse button click.
2. use TAB to cycle through the graphic object then right-click to operate on it (align, size, position).
This tip I have found on the Internet and tried it.
I used playing around with the 2 values BorderWidth and PaddedBorderWidth found with Regedit in the key HKEY_CURRENT_YSER\Control Panel\Desktop\WindowMetrics.
After setting BorderWidth to -50 and PaddedBorderWidth to 0.
The result was that the borders remained approximately 1 pixel wide, but once you selected it, they are shown wider.
Still no solution for the fore mentioned primary question though.

Flex: Simultaneous touch in one app?

I have an app with several buttons running on a touch screen (Windows 7) - can I make the app respond to a user touching 2 different buttons at the same time? Or will only one of the buttons respond?
I don't need any gestures and have set the inputmode to touch_point. My test shows that it supports touch events and have 10 max touch points. But to add touch_tap to the buttons does not make both buttons react.
Any hints would be most apreciated!

WinRT FlipView Scrolling Event

Is it possible to know, when a FlipView is sliding back or forth, what item is currently on screen? The only relevant event I can see is SelectionChanged, which only gets raised when the FlipView comes to a rest and not if the person is quickly flipping through multiple items. I want to implement a "page number" indicator that changes even when the FlipView has not come to a rest. I'm using C++/CX.
You could check the ScrollViewer that is part of the control template of the FlipView. To get hold of the control - you would use the VisualTreeHelper to scan the visual tree looking for it. Then perhaps the ScrollViewer's ViewChanged event would let you see if the FlipView was manipulated.
If all you want to do is show a page number, you could DataBind the TextView displaying the number to the FlipView's SelectedIndex property. You'll need to create a ValueConverter that adds 1 to the SelectedIndex, but that'll only take a minute.
