I have installed Hotspots for Joomla on the latest stable release of Joomla. I have made several test installations and it´s the same problem. I have installed booth on local servers on my laptop and on some different servers at server providers. I have tried the Joomla native layout and other layouts from layout providers. The behavior is the same.
Adding a single hotspot at front end

When trying to ad dates for start publishing and finish publishing at front end there are no visible dates in the textboxes attached to the date picker. It´s not possible to type any letters or numbers inside the textboxes. The date picker seems to work but the date to be picked will not be displayed in the text box.

Anyway, the date chosen by the date picker seems to be stored correctly in to the database. If later on watching at backend, the dates of start publishing and finis publication are there visible.
When to watch “my hotspots” in edit mode in front end there is no dates visible but when doing “mouse over” on the textboxes the dates are displayed.

How to fix this?
