Strange behavior of DateTime

I have a long and often-used app that contains two DateTime controls. Until today, when I click on part of the date or time, the relevant numbers get highlighted and then I can type in the new information.

Today the highlighting stopped: the text actually does get selected and typing in a new date or time works if I’ve clicked in the right place, but I can’t tell that I’ve clicked in the right place.

The only thing that I’m aware of changing is that I updated Chrome this morning?

Any wisdom on why this is happening or how to get the highlighting back?

Thanks

Which DateTime control are you using?

Some DateTime controls use the native datepickers which are built into the browser. These are not covered by the standards, so they will have differences on various platforms.
