I have an on-timer script running in a hidden window that checks for internet connectivity every 15 seconds. Works very nicely.
In a user window (where the script is definetely not running) the user enter field with a pop menu. If the timer script fires while the user in thinking about which item to choose, the pop up menu collapses, but the field with the pop remains the active field.
Also if the user is typing in a text field they get kicked out of it
On OSX neither of these things happen.
Can anyone confirm
Also, with respect, please no replies with speculative workarounds you have not actually tried.
