The issue is reproducible. jQuery issued a patch for this a month or two ago, I have not seen anything from prototype. To reproduce in IE8Have a click method that calls a messagebox with a callback, like this:
procedure click
thisform.wmessagebox(wformcallback,blah, 36)
Then in the wformback call another messagebox with no callback
In IE8, and only IE8, sometimes on .wmessagebox calls I get this js error:
Webpage error details
Message: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
Line: 1
Char: 25361
Code: 0
URI: http://localhost/awScripts/FoxInCloud.js
The dialog message box is open and displayed, but will not accept clicks or input, in effect stranding the user on that dialog.
It never happens in IE9, FF, Chrome.
Unfortunately IE8 support is an absolute requirement for this project, all the end user workstations run XP and IE8
Any ideas?
