Through ages of google searching we found a work around online, adding a window.setTimeout() around the alert box, eg:

ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "validationAlert", "window.setTimeout(\"alert('Just testing')\", 0);", true);

Hope this saves some other people time and heart ache.
