When I create a few similar pages I tend to create the first page, "Save-As" page1.php, make some changes and then "Save-As" page2.php etc. I have notice in WB2015 that when I save-as page 2, page1.php no longer exists, the file has been deleted (or renamed), is that right? I can see that becoming a major issue as I often make a few changes and "Save-As" to save as something else with the intent of keeping the original.

I appears that this only happens if I use a tilda (~) at the beginning of the filename, which I often do for files I want at the top of my filelist sometimes... I'm guessing WB is seeing them as some kind of temp file and deleting them? Any chance of a fix?
