Version 2.50+ Build 160425 released

This is still broken with the same behaviour on 160426

I found the issue;

line 191, templateeditorbar_view.php:

<select class="listboxtemplates form-control" id='listboxtemplates' name='screenname' onchange="javascript: window.open('<?php echo $this->createUrl("admin/templates/sa/view/editfile/".$editfile);?>/screenname/'+encodeURI(this.value)+'?templatename=<?php echo urlencode ($templatename); ?>', '_top')">

createURL returns a URL that already contains one '?' on servers without mod_rewrite (like my IIS server), so the ?templatename= should, in that case, be &templatename=.
This is on the screen switcher, but the same applies to the actual template switcher, which is on line 184.

If I modify the HTML with Chrome's Inspector to change ?templatename= to &templatename=, it works flawlessly.

It also works with /templatename/ in place of ?templatename=, which might be the cleaner option, with less edge cases that depend on webserver type and features

I can confirm that this is the behaviour I see as well. The URL is malformed. On IIS, this URL is opened:

http://xxxxx/forms/index.php?r=admin/templates/sa/view/editfile/startpage.pstpl/screenname/welcome?templatename=my-template

Which contains indeed twice a question mark...

The problem is exist in latest version. I m comfirmed.
