viewFactory:simple_list() freezes if it is initially disabled when the dialog first starts and then enabled later as the result of a user action. This happens on Windows 10 and Windows 8.1, with CC 2015.10.1 and 5.7.1. It doesn't occur on OS X.
To reproduce:
1. Run the following script:
local LrBinding = import 'LrBinding'
local LrDialogs = import 'LrDialogs'
local LrFunctionContext = import 'LrFunctionContext'
local LrView = import 'LrView'
local bind = LrView.bind
local f = LrView.osFactory()
LrFunctionContext.postAsyncTaskWithContext ("", function (context)
local prop = LrBinding.makePropertyTable (context)
prop.cb = false
local items = {}
for i = 1, 10 do table.insert (items, {title = i, value = i}) end
local controls = f:column {bind_to_object = prop,
spacing = f:control_spacing (),
f:checkbox {title = "Enable simple list", value = bind ("cb")},
f:simple_list {items = items,
enabled = LrBinding.keyEquals ("cb", true)}}
LrDialogs.presentModalDialog {title = "Simple List Bug",
contents = controls}
end)
2. Click the checkbox and notice that though the simple_list control appears enabled, you can't select any items or scroll it.
3. Change the line "prop.cb = false" to "prop.cb = true".
4. Run the script and notice that the simple_list control properly enables whenever the checkbox is checked.

simple_list() has lots of other problems -- it needs some love:
